Health Secretary Matt Hancock has stirred up a bit of a reaction from history buffs on Twitter.

In a tweet, he celebrated the centenary anniversary of Nancy Astor being elected as an MP.

Mr Hancock says she was the first female MP to be elected, but as people are pointing out in his replies, she was actually the first female MP to take her seat.

The first woman to be elected, external to the Commons was Constance Markievicz in 1918 - but as a member of Sinn Fein, she did not take her seat.

Sir Clive Cowdery, a millionaire businessman and philanthropist, says he has switched his vote from Tory to the Liberal Democrat’s because of his concern about the future economy under the Conservatives.

Today he appeared at a Liberal Democrat event to introduce Jo Swinson and appealed to other Tory voters to follow him vote Lib Dem to avoid a "reckless" financial future.

A Conservative source points out, though, that he described himself as "centre left" back in 2011.

Boris Johnson's election campaigning has taken him to Chulmleigh College in Devon.

The prime minister joined in with a rendition of "a lovely day" with the school choir, as well as taking a turn in the lab.

It's a plague on all your houses - but for very different reasons.

The main criticism of Labour is that is spending on investment is just so big, it wouldn't be able to deliver it.

The group also says it is highly likely the party's tax rises would impact, directly or indirectly, on more than just the top 5% of earners.

There's no respite for the Conservatives though - particularly on their pledge not to extend the transition period included in the PM's Brexit deal beyond 2020, even if a trade deal has not been agreed.

The idea that the UK might have to trade on World Trade Organisation terms is seen by these economists as something which would be highly damaging to the economy.

It says this could cause an increase in the deficit of the same order, potentially even higher, than would be caused by Labour's tax and spending plans.

Chancellor Sajid Javid has responded to the IFS's criticism of Conservative economic plans by attacking Labour.

Referring to a Labour plan to scrap a tax break for married couples, Mr Javid said Jeremy Corbyn’s plans "would mean millions people more paying higher taxes".

"With no position on Brexit and no plan to how to pay for his £1.2trn spending spree [Mr] Corbyn simply doesn’t have any credibility left."

“[Mr] Corbyn can’t pretend that it’s only the rich or businesses that will pay the price for his plans...

“Only a majority Conservative government will get Brexit done and unleash our country’s potential delivering the change people voted for in the referendum.”

Shadow chancellor John McDonnell has responded to the IFS's assessment of Labour's spending plans.

He adds: "What is also clear from the IFS is that under the Conservatives there will be no change and austerity will continue to undermine our public services."

Jeremy Corbyn is asked about the claims from the Institute for Fiscal Studies that neither Labour nor the Conservatives were offering "credible" spending plans.

He responds by describing his party's manifesto as, bold, ambitious and thought out.

He says Labour has "taken on board" the comments from the IFS, adding: “No other party has produced a costed manifesto. No other party has put themselves up for that kind of scrutiny".

He says his party is "very happy" to have that kind of scrutiny and is "very confident" that its manifesto can deliver improvements in the "lifestyle and life chances" of the very poorest people in the UK and will not result in tax or national insurance increases for anyone earning less than £80,000 a year.

He has now finished taking questions.

Jo Swinson, the Lib Dem leader who is currently speaking at an event in London, has also taken aim at Boris Johnson for not caring about jailed British-Iranian mother Nazanin Zaghari-Ratcliffe.

In November 2017, then Foreign Secretary Boris Johnson had to apologise after he was criticised for suggesting Mrs Zaghari-Ratcliffe was training journalists - something her family and employer say is incorrect.

"Boris Johnson only cares about Boris Johnson," she says. "He will do whatever it takes, sacrifice whatever or whoever is needed to get what he wants.

"His life has been about becoming prime minister. Not out of some burning desire to make people's lives better, but out of some sense of Etonian entitlement, because it's what people like him get to do."

Speaking at a campaign event billed as "The Problem with Boris" in London, Lib Dem leader Jo Swinson says the Tory leader has "dragged the office of prime minister through the mud".

She says he is "not fit to be prime minister", accusing him of being "complicit in stoking division and fear in our communities".

She asks "why else" would Tommy Robinson be supporting him, referring to comments made by former English Defence League leader earlier this month.

"Honestly, such an endorsement would shame any decent person," she says. "But Boris Johnson has no shame when it comes to the language he uses about race.

"Just this week the Muslim Council of Britain accused Boris Johnson's party of denial, dismissal and deceit over Islamophobia."

Mr Johnson said at the time that party members guilty of Islamophobia "are out first bounce".

At a speech in London, the Liberal Democrat leader Jo Swinson says her party still poses a challenge to the Conservatives in dozens of seats - and could stop Boris Johnson winning an overall majority.

She says: “There’s a huge amount to play for.”

Ms Swinson explains polls show her party either in the lead or second place in 134 seats.

The Liberal Democrats promised to revoke Article 50 if they entered government but in recent days have stressed their potential role in forcing another party to hold a new referendum.

Jo Swinson denies the "revoke" strategy had backfired saying: “Our policy was very honest and straightforward.”

She points out that the Liberal Democrats voted 17 times for amendments to hold a further referendum.

She is speaking at a homeless shelter in London, highlighting the Liberal Democrats plans to spend an extra £6bn on welfare.

In a Q&A following Jeremy Corbyn's environment speech, he is asked about suggestions that Labour will change its election approach and shift its focus north to target Labour supporters who are considering voting for the Tories over Brexit plans.

Mr Corbyn says the Labour campaign is in every part of the country, and he will continue to travel around the UK.

He says: "I say the same thing at every place. I don’t have one message for one group and one message for another."

He then lists the reasons why people should vote Labour, including inequality, and its approach to the environment.

Asked about Labour’s plan to plan two billion trees, he says he is “conscious” that it is “very ambitious” but says “the land is available” and can be done by 2040.

He adds that he’d plant a hornbeam tree in Downing Street garden.

A new poll on Wednesday suggested the Conservatives would get a 68-seat majority, if the election was held tomorrow. Why has the poll stirred up so much interest?

The reason everybody is so interested in this poll is that when YouGov used the technique in 2017 it anticipated quite a seriously hung Parliament against the trend of much - although not all - of the other polling.

This time, what YouGov has come up with is very, very much in line with what we would have expected from the polling we've been seeing over the course of the last three or four weeks.

The poll is saying in terms of the outcome, in terms of votes, the Conservatives look as though they have an 11-point lead over Labour. That indeed is more or less what YouGov itself has been saying in its last three or four polls and it's very close to the average of the polls in the industry as a whole.

And its seat forecast of about 359 is not that far different from what you would have said the outcome was likely to be if you had simply taken the fact the Conservatives are seemingly more or less at the same point as they were two years ago across the country.

Crucially, although this poll does confirm what we suspected was true, that the Conservative vote is going up more in places that voted strongly to Leave than it is in places that voted strongly to Remain, the net effect of that could well be almost close to zero.

What I mean by the net effect is the seats that the Conservatives are picking up in very strongly Leave areas where the swing to the Conservatives is higher, is evidently being more or less counter-balanced by the fact there are other seats which voted to Remain where the Conservative position is rather weaker than it was two years ago.

If there is a surprise in this poll it is indeed suggesting that the Liberal Democrats are not going to come up with much in this election suggesting only 13 seats, only one more than they got in 2017.

The other crucial message of this poll... yes, at an 11-point lead the Conservatives look like they should win the election relatively comfortable, but if in the next two weeks the Conservative lead in the poll should fall back to around seven points then the election could suddenly look much closer and at least the possibility of a hung Parliament would come back into view."

In the 2015 election and the 2016 EU referendum, migration was a huge issue for voters - but the overall number of EU citizens moving to the UK has fallen to its lowest level for 16 years, while the UK's net migration rate remains more than 200,000, ONS figures show.

Net migration - the difference between how many people came to the UK for at least 12 months and how many left - was 212,000 in the year to the end of June.

EU net migration dropped to 48,000 - its lowest level since 2003.

The ONS says this was down to fewer people coming to Britain for work.

Jeremy Corbyn finishes his speech by saying Labour's "plan for Nature" is a "radical and innovative" response to the climate emergency.

"Together, we can change course and leave a country and a planet that’s fit for the next generation."

He says no other party has produced such a comprehensive plan for the environment - and then jokes that people should read it online to save paper.

He will now take some questions from the press.

Meanwhile, a Brexit Party campaign event is under way in Hull, where Nigel Farage is due to speak shortly.

"Of course Brexit is their main message," says BBC reporter Frankie McCamley. "Here 67% of people voted for Brexit so they're really trying to get those Labour Leave voters.

"They've also got really strong criticism of the whole voting system itself," she says, saying the party wants to reform it in their "contract with the people - they're not calling it a manifesto, they don't like that word".

Mr Corbyn says that a Labour government will create 10 new national parks as part of its "Plan for Nature".

He says the new national parks would come during its first term – with areas being considered including the Malvern Hills, Chiltern Hills, Lincolnshire Wolds and North Pennines

He outlines Labour's other proposals, which are:

• Aiming for 75% of the population in England to live within half-an-hour of a national park or an area of outstanding natural beauty
• Two billion new trees in England by 2040
• It will make £2.5bn available to plan trees in sites including urban parks, farmland and schools
• It will never allow the return of fox hunting.
• A new Clean Air Act, encouraging cleaner transport and clean air zones around our children’s schools

Moving on to the environment, Mr Corbyn says he's "deeply moved" to see some of the school children who have been striking over the climate in the audience.

He says its "humbling" to see children teaching the adults a lesson.

Mr Corbyn adds he's proud that Labour has responded by leading the Parliament to become the first in the world to declare a climate and environment emergency.

"The reality is this election is our last chance to tackle the climate and environment emergency," he says.

We have more from the DUP's launch of its manifesto in Belfast today.

The party has reiterated its opposition to Boris Johnson's Brexit deal, with deputy leader Nigel Dodds saying unionists in Northern Ireland are united in opposition to it.

He said there can be no borders in the Irish Sea, adding: "We will work to try to get a sensible Brexit deal. But it cannot erect new barriers.

"We need our people to come together, not create more division."

Of the border checks in Mr Johnson's deal, the DUP manifesto said: "The East-West checks as proposed would lead to excessively bureaucratic burdens for trade between Great Britain and Northern Ireland and consequently higher prices and less choice for consumers as GB businesses opt for 'not available in Northern Ireland'."

Mr Dodds himself is defending his North Belfast seat against a pro-Remain Sinn Fein candidate.

Read our full story covering the DUP's launch here.

Before getting on to the subject of the environment, Jeremy Corbyn starts by saying it would be remiss of him not to say a few words about Donald Trump and Boris Johnson.

Yesterday, Mr Corbyn claimed he had "proof" the NHS was at risk under a post-Brexit trade deal with the US.

He says those revelations “absolutely shredded” all of Mr Johnson’s denials that the NHS wasn't on the table in trade conversations with the US.

“This election is now a fight for the survival of the NHS as a public service.”

He says you can vote Tory to “sell out the NHS” or vote Labour to save the NHS.
