Green Party co-leader Jonathan Bartley will take part in a Q&A on BBC 5 Live and the News Channel from 09:00 GMT this morning - something Boris Johnson and Plaid Cymru leader Adam Price did earlier in the campaign.

Mr Bartley will answer a number of questions from BBC audience members live on air.

He was also interviewed on BBC Breakfast this morning - that interview can be watched via the tweet below.

Education Secretary Gavin Williamson is asked about reports that the Tories are threatening to review Channel 4's broadcasting licence following the row over the ice sculptures.

"Channel 4's licence is up in 2024 so whoever is in government will be reviewing it but that is just part of the course of what goes ahead," says Mr Williamson.

"But an official complaint has been made to Ofcom, I think that's the appropriate and proper way to deal with the situation."

Is that a threat? "Well the licence has always been there to be reviewed in 2024 so there's absolutely no change whatsoever in terms of that," he replies.

Labour is today launching a regional manifesto for each part of the country, including pledges on transport, housing and jobs.

The party is promising an "investment blitz" across England to bring "wealth, power and prosperity" to communities.

Each manifesto will outline plans for individual regions, with most of the pledges to be paid for by Labour's £250bn Green Transformation Fund.

The pledges include a number of transport projects, such as:

• Northern Powerhouse Rail - improving connections between Liverpool, Manchester, Leeds, Hull, and Newcastle, and cutting journey times
• Investment in the Midlands Mainline railway
• Electrification of lines around Bristol Temple Meads

Education Secretary Gavin Williamson has been defending Boris Johnson for refusing to attend Channel 4's climate change debate yesterday - and attacks the broadcaster for not letting his colleague, Michael Gove, take his place.

"It was bit of a shame that Channel 4 decided to use a gimmick of an ice block not just for ourselves but also for the Brexit Party," says Mr Williamson

"The prime minister is very much engaged in a whole range of debates, he's been on ITV, he's going to be on another one.

"He's hoping to be on Andrew Marr at the weekend as well.

"So there's an awful lot of opportunity to have a debate, ask the prime minister questions. But there's only so much time that he has to be able to do them all."

Asked what could be more important for Mr Johnson to do rather than attending the debate, Mr Williamson says he was "out in the country campaigning" and "getting our message out there to get Brexit done".

He adds that Michael Gove - who attempted to take part in the debate instead of Mr Johnson - "has done more for the environment than than any other politician".

"Many other TV debates that go on, you're allowed to field a substitute. I think there was a little bit of grandstanding and playing politics there. It's a shame they chose to do that and I hope they wouldn't do it in the future."

Mr McDonnell is also asked about suggestions that Labour is changing its campaign strategy to target Leave-voting areas - something which he denies.

The claims follow a YouGov poll on Wednesday that suggested the Tories were on course to win a majority by picking up votes in Labour seats which voted for Brexit.

The shadow chancellor says: "There's no change in strategy. I don't know where this story has come. People have put two and two together and made five.

"We are simply rolling out our plan to make sure that everyone understands our Brexit strategy."

So what is Labour's strategy? Read more about the party's plans here.

Shadow chancellor John McDonnell says the prime minister is “running scared” from a BBC interview with Andrew Neil.

The leaders of Labour, the SNP, the Lib Dems and the Brexit Party have all agreed to be questioned for 30 minutes by the journalist, but Boris Johnson has refused to say whether he will take part.

Mr McDonnell says his understanding - and that of the other political parties - was that there would be a sequence interviews with each leader.

He says it is a “matter of honour” and that Mr Johnson is “playing the BBC”.

"He knows that Andrew Neil will take him apart. He is running scared. Even if he does it now, he's played you (the BBC) because he's pushing it later and later beyond the postal vote returns."

He adds that the BBC "should be as angry as we are".

If you care about what the parties are promising on the NHS, here are some key issues to watch for.

Here's a little more from former Tory minister Ed Vaizey, who says it is "not a sensible strategy for political parties to threaten broadcasters".

That follows reports that Conservative sources briefed some journalists that "if we are re-elected we will have to review Channel 4's public services broadcasting obligations".

The party is embroiled in a row with Channel 4 over the broadcaster's decision to "empty chair" Boris Johnson during its election debate on climate change last night.

He says: "It's not a sensible strategy for political parties to threaten broadcasters in that way, so I was disappointed.

"It was an anonymous briefing, I don't think it's the settled view of the Conservative Party or the government."

The Conservative’s Ed Vaizey, a former technology and culture minister who is standing down at this election, says everyone has got “a little overheated” over Boris Johnson’s decision not to take part in the Channel 4 TV debate.

He says the Tories were free to decide whether their leader participated and the decision to place an ice sculpture on the PM's podium was “a stunt too far”. However, he adds that he understands the broadcaster was “annoyed”.

He tells Today: "For some reason in this election, the media is indulging in quite a lot of navel gazing. We have endless stories and debates about which people are going to participate in their debates, whether it’s on Sky, or the BBC or ITV or Channel 4."

He says there is a risk-benefit calculation for parties to decide which TV debates their leaders should be involved in.

But he says any decision can “backfire”, citing the example of Theresa May choosing not to participate in 2017 as he says it played into a narrative that she was running scared.

SNP leader Nicola Sturgeon took part in last night's climate debate on Channel 4 - and she then told ITV another debate was needed. One that involves the future of the monarchy in the UK.

She made the comments in the wake of the controversy over the Duke of York.

Prince Andrew stepped down from public duties after mounting pressure following his BBC Newsnight interview about his friendship with convicted sex offender Jeffrey Epstein.

Ms Sturgeon said a debate about the monarchy should not be a distraction from Epstein's victims. However, when asked if the issue made her consider whether the monarchy is fit for purpose, she replied: "I think it raises a number of questions.

"I think there is a debate to be had about the longer-term future of the monarchy, one of the things though in the context of Prince Andrew that I feel very strongly about is that a debate about the monarchy shouldn't be a distraction from Epstein's victims and how they now get whatever justice they can get and get the truth and the ability to move on."

The BBC's Jessica Parker explains Boris Johnson's "empty chair" and Thursday's election campaigning.

BBC Breakfast

As we mentioned earlier, Green Party co-leader Jonathan Bartley will be taking questions from the audience on the News Channel and Radio 5 Live later, but first he's been on the Breakfast sofa.

He says Boris Johnson’s refusal to take part in Channel 4’s climate change debate shows that he’s “completely unfit” to be prime minister.

The PM’s failure to engage in the discussion “speaks volumes”, he says, and showed “contempt for the next generation".

He adds: “It’s so disappointing that we face this climate emergency – the biggest existential threat to this country – and the prime minister wouldn’t show up.”

Mr Bartley says the government “must be held to account” over its failure to take its commitment to the environment seriously.

Here is more detail on what the Conservatives are pledging on the environment.

Reality Check

A lot of talk this morning is about Boris Johnson's absence from the climate change debate, but what came up in the debate from the five party leaders who did take part?

Reality Check has been looking at some of the claims made in the debate, including the one below:

Claim: Jeremy Corbyn said: "We have the lowest level of tree cover of almost any country in Europe."

Reality Check: The Labour leader made this claim while talking about his party's plans to plant two billion trees by 2040 - something we've looked at in a separate piece.

In total, 13% of the UK is covered by trees, which is well below the European Union (EU) average of more than 30%.

A few European countries have even lower levels of tree coverage: Ireland has 11% and Malta has almost none.

Read the full analysis here.

There is widespread interest in last night's Channel 4 leaders' debate on climate change - not so much for the subject under discussion, but the station's refusal to allow the former environment secretary Michael Gove to stand in for Boris Johnson and the decision to replace the prime minister with a melting ice sculpture.

According to the HuffPost UK website, the PM's father, Stanley Johnson, also turned up and offered to take his son's place, external.

The BuzzFeed News website says the Conservative threat to reassess the station's public service broadcasting licence if they win the election is a dramatic escalation, external of the war of words between the Tories and Channel 4.

Green Party co-leader Jonathan Bartley will be on BBC Radio 5 Live and the News Channel from 09:00 GMT this morning to answer questions from the audience.

On Wednesday, Plaid Cymru leader fielded questions on Boris Johnson and Jeremy Corbyn.

And earlier this month the PM also took part in an hour-long BBC Q&A - you can watch video on BBC iPlayer.

Here's a quick look at some of the main stories making the headlines first thing:

• A row has broken out over Channel 4's decision to "empty chair" Boris Johnson last night during its election debate on climate change. Minister Michael Gove offered to take the PM's place for the Conservatives, but the broadcaster said the invitation was for leaders only. The party have written to Ofcom saying placing an ice sculpture on Mr Johnson's podium was a "provocative partisan stunt"
• Meanwhile, Mr Johnson has refused to say whether he will take part in a BBC interview with presenter Andrew Neil. When asked several times if he would appear, the PM said he would have "all sorts of interviews with all sorts of people"
• The focus for the Tories today is England's education watchdog Ofsted. Mr Johnson will announce plans for longer inspections and an extra £10m of funding as part of their aim to strengthen Ofsted. Opposition parties want a new body
• Labour will be talking about an "investment blitz" across England to bring "wealth, power and prosperity" to communities. They will launch a regional manifesto for each part of the country, including pledges on transport, housing and jobs

• Meanwhile, the BBC has asked the Conservatives to remove a Facebook advert that uses edited footage of its news reporters and presenters, saying the material was taken out of context. It was first shown yesterday afternoon

Hello from Westminster, and welcome to our coverage of all the twists and turns of the election campaign.

Without even showing up, the Conservatives have stolen the headlines from last night's TV debate on climate change.

Will Boris Johnson show up for an interview with the BBC's Andrew Neil? That question remains unanswered.

And the TV debates keep on coming. Senior members of the Tories, Labour, Lib Dems, SNP, Greens, Plaid Cymru and the Brexit Party will take part in a debate tonight on BBC One.
