It's a busy morning for the party leaders travelling here, there and everywhere.

Liberal Democrat leader Jo Swinson has spent time sparring at the Total Boxer gym in north London.

She was there to talk about her party's plan to cut violent crime by investing £500m a year in youth services.

As she threw punches towards one of the gym's trainers, she was wearing a "girly swot" T-shirt - a reference to a jibe that Boris Johnson made against David Cameron.

Our correspondent Tom Symonds was there watching and got the above action shot...

Shadow chancellor John McDonnell begins a speech in London on Labour's NHS plans, but first criticises the Tories for spreading "fake news" about his party's spending plans.

He also accuses Chancellor Sajid Javid of "running scared" of taking part in a televised debate with him. Channel 4 had hoped to hold one, but reports suggest Mr Javid has been hard to pin down.

Boris Johnson's second visit to the flood-affected area comes as the topic has become a key issue in this week's election campaigning.

Yesterday the prime minister, who visited Matlock on Friday, announced more support for communities affected by flooding following a meeting of the government's emergency Cobra committee.

It followed criticism from Labour and the Liberal Democrats, whose leaders met victims affected by the flooding yesterday.

Mr Johnson arrived in Stainforth as nearly 100 soldiers began assisting communities cut off by the flooding.

The floods began last week after a dramatic and sustained downpour saw South Yorkshire receiving the equivalent of a month of rain in just one day.

Fishlake near Doncaster has been one of the worst hit with hundreds of people being forced to leave their properties.

With Boris Johnson having already faced some anger in South Yorkshire and Jo Swinson getting a bit of grief in London, it's now Jeremy Corbyn's turn.

On his arrival in Glasgow he faced a heckle from a protester accusing him of sympathising with terrorists.

It follows former Labour minister Tom Harris calling on voters to back the Tories because he claims Mr Corbyn is a danger to the UK's security.

A little more from South Yorkshire, where Boris Johnson says he didn’t underestimate the impact of the floods in northern England.

He says: “If you look at what’s been happening since the flooding began, there’s been round the clock monitoring of the situation - both at a local and national level."

Labour leader Jeremy Corbyn yesterday called the government response to the situation "woeful".

On to other election issues, Mr Johnson is asked about his former colleague David Gauke’s comments that a Conservative majority at the upcoming election would be a "bad outcome for the country".

He responded by saying: “We’re fighting for every vote that we can get. I regret that we haven’t got his support but we’ll do our best in the campaign.”

We've now heard from the PM out and about in the flooded part of the country.

Boris Johnson says he "perfectly understands" some of the negative reaction his visit to South Yorkshire.

Earlier, one woman refused to talk to him, while some onlookers could he heard shouting "you took your time" and "where have you been?"

Mr Johnson said: "You cannot understimate the anguish that a flood causes. The shock of seeing your property engulfed by water is huge - and also the anxiety about what may still be to come."

He thanked the emergency services and the army, but he says “there is a lot more still to be done.”

That was quick. Just a few hours ago, Chris Davies was announced as a Tory candidate despite his conviction for a false expenses claim. Now he is standing down.

A Tory source tells the BBC the selection for the constituency in North Wales has been "seriously flawed and chaotic".

Mr Davies says: "Given the reaction in the media to the idea of me being a candidate, I have decided to pull out of the selection process."

Earlier this year, Mr Davies lost a by-election which had been triggered by a recall petition.

In March, he admitted to creating fake invoices over the purchase of £700 of pictures and offered an "unreserved apology".

There's been a lot of talk about tactical voting this election, with people wondering the best way to vote in order to further their preferred position on Brexit.

Now the People's Vote campaign, which has pushed for another referendum, has produced a tactical voting guide on its website, recommending more than 100 candidates to prevent the Conservatives pushing through their Brexit plans.

Among those it urges voters to support are former Tory minister Dominic Grieve, who is standing as an independent, Liberal Democrat Chuka Umunna and Labour's Rosie Duffield.

The cross-party People's Vote campaign says it will lend financial and campaigning support to these candidates in seats it claims will decide the election.

One notable omission is Anna Soubry, who left the Conservatives for Change UK over Brexit, and who held her seat by a majority of 863 in the last election.

The People's Vote says candidates were selected using "sophisticated analysis" of private and public polling, including constituency specific data.

Amid all the election news, we're also waiting to hear a High Court decision today on whether a strike by Royal Mail workers can go ahead.

The strike could disrupt postal voting as well as the Christmas post.

In a ballot, 97% of the 100,000 Communications Workers Union members voted for the strike, but Royal Mail has gone to court claiming there were "potential irregularities" - which the union denies.

The strike was called because the union says Royal Mail has failed to stick to an employment deal from last year. The company disputes this.

Boris Johnson isn't the only one meeting some resistance this morning, as our team on the ground in Crouch End, London, tell us.

A small group of anti-austerity campaigners have gathered outside the venue where Jo Swinson will hold a campaigning event.

They are planning to hold a minute's silence when she arrives to “commemorate the 130,000 victims of austerity”.

They say that Ms Swinson should shoulder some blame for those cuts as a former member of the Conservative/ Lib Dem coalition government.

The group identify themselves as local residents and friends. One of them is a member of the Labour Party, but they are not here as Labour supporters.

Boris Johnson has been meeting some of the victims of the floods in South Yorskhire.

On his walkabout, though, some onlookers could he heard shouting "you took your time" and "where have you been?"

A woman working to shore up flood defences snubbed Boris Johnson’s attempt to talk to her about the work.

The audio was a bit indistinct but she can be heard saying "I’m not talking to you" and "you’ve not helped us”.

Prime Minister Boris Johnson has begun his day by making a visit to South Yorkshire to see the impact of the recent flooding.

It comes a day after he responded to criticism by announcing more support for communities affected following a meeting of the government's emergency Cobra committee.

Boris Johnson will speak later at an electric car manufacturer to promise a future Conservative government will harness the power of technology to "drive a clean energy revolution".

His narrative is that clean technology will get us out of the problem of climate change.

But the trouble is experts say switching to electric cars won't be enough because it takes so much energy to mine material for batteries and to build cars. More electricity has to be created to power the vehicles too.

It is also essential to reduce the size of cars to reduce the weight (the opposite is happening under the SUV boom) - and we also need to reduce the demand for driving full-stop, through better public transport and more active travel.

Politicians tend to shy away from telling the public harsh truths about what’s really needed to address climate change - especially during an election campaign.

And the same goes for housing, too. A mass insulation programme to reduce energy demand is essential if we are to meet climate targets - that would cost a lot of money.

Baroness Warsi, an outspoken critic of Islamophobia in the Conservative Party, says she will still support the party in this election, despite its "institutional problem" with the issue.

She tells Today: "I can’t be of the Ian Austin view," referring to the former Labour MP who has backed the Tories in protest at allegations of anti-Semitism in his own party.

"I can’t realistically say I would like people not to vote for my party mired in allegations of racism and vote for another party mired in allegations of racism."

After senior minister Michael Gove reiterated that the party would investigate "Islamophobia and other forms of prejudice" rather than focus on hatred against Muslims, she says she has to accept what is being offered. "Beggars can’t be choosers any more."

But she says over four years, with three party chairman and two prime ministers, the party has been "dismissive" of Muslims' reports of "the most vile racism at every level".

The party today says it is taking swift action against 25 sitting and former councillors accused in the Guardian of posting racist and Islamophobic material, external, but Baroness Warsi says in earlier cases people are readmitted to the party when the media moves on.

There is a "complete lack of transparency" over the number of allegations and the action taken against Islamophobic members, she says.

• The Lib Dems pledge more money for youth services
• And the Greens will be setting out their ideas for a "carbon chancellor"

Just nipping back to this morning's media round for a moment, shadow health secretary Jonathan Ashworth had some interesting things to say on freedom of movement.

Challenged about the impact of Brexit on health services, which he described as a "huge, huge risk", he said Labour would "retain freedom of movement for the NHS".

He says if an NHS trust believed an EU national should be recruited, "we willl not stand in their way" - whereas the government has "put so many obstacles and bureaucracy" in the way. Their families would also be allowed to come to the UK, he says.

About 10% of doctors and 6% of nurses are currently recruited from EU nations.

Labour's Luke Pollard, who is running for re-election in Plymouth Sutton and Devonport, says his office was was daubed in "homophobic graffiti" last night.

Mr Pollard has previously been targeted by vandals, who wrote "anti-gay slurs" on his office in Plymouth.

In the video he posted on Twitter, he says he has previously offered to sit down with the people who carried out the graffiti but the request has been ignored.

Speaking of deals, pacts and tactics, our colleague Philip Sim, from BBC Scotland, has been looking at why there's little evidence of them happening there.
