Brexit news - live: Theresa May heads to France amid howls of outrage from Tory Brexiteers at 'surrender' over customs union

Welcome to our coverage of the ongoing Brexit crisis

Michel Barnier, the EU's chief negotiator, will hold talks with Irish leader Leo Varadkar in Dublin later today.

Their meeting comes ahead of a crucial EU summit on 10 April, when leaders will meet to discuss the UK's request for another extension in the Brexit process.

The UK is currently scheduled to leave the EU on 12 April.

Mr Barnier will also meet Ireland's deputy premier and foreign affairs minister Simon Coveney and finance minister Paschal Donohue.

Andy McDonald, the shadow transport secretary, has suggested a second referendum is the likeliest outcome of ongoing cross-party talks.

"There's divergence of opinion, let's be absolutely straightforward, people take different views on a public vote - be that a general election or a second referendum - but that is not where we are," he told the Today programme.

"My view is if our proposition was accepted in its totality I think the argument for a public vote in those circumstances reduces."

"The reality is that is not on the table, so I think we're looking at options that would warrant a PV (People's Vote) in those circumstances.

"We've got to look at the offer on the table at the moment and what we're looking at is Theresa May's deal or no deal."

Theresa May has repeatedly ruled out calling a second public vote on Brexit.

The shadow transport secretary has said he is "delighted" that the Jewish Labour Movement (JLM) will remain affiliated with the Labour Party.

Members of the JLM passed a motion during the group's annual general meeting on Sunday declaring the Labour Party leadership antisemitic. The group also said that Jeremy Corbyn was “unfit to be prime minister”. 

Andy McDonald told the BBC he couldn't accept the allegation that Mr Corbyn was antisemitic.

Our political correspondent Benjamin Kentish has more about the JLM's decision here: 

Solicitor general Robert Buckland has set hares running by suggesting that Theresa May could be prepared to cave in to Jeremy Corbyn's customs union demands.

Labour held talks with the government last week to find a way through the Brexit impasse. However the negotiations ground to a halt on Friday, with angry recriminations over the prime minister's apparent refusal to compromise.

Mr Buckland appeared to pave the way for some sort of movement, telling the BBC's Westminster Hour that a customs union "does mean that we deliver an end to freedom of movement and it does mean that we deliver the vast majority of the aims of Brexit, which was to leave the institutions of the European Union".

"It's not perfect but, frankly, in this particular hung parliament none of us can get perfection, we need to compromise."

He said that "something approximating a customs arrangement or customs union would be the most likely outcome" of the process.

But in a sign of deep divisions among Conservatives, former foreign secretary Boris Johnson used his Daily Telegraph column to warn that Tory MPs would not allow Mrs May to "surrender" to Mr Corbyn.

"If the UK were to commit to remaining in the customs union, it would make a total and utter nonsense of the referendum result," he said.

"To agree to be non-voting members of the EU, under the surrender proposed by Jeremy Corbyn - it cannot, must not and will not happen."

One of the biggest stories of the morning is - shockingly - not Brexit. The government has published its long-awaited white paper on digital harms, where it outlines a crack down on social media giants.

Tech companies such as Facebook and Twitter will be legally required to protect their users under government plans to introduce a regulator.

The proposal, which would also see bosses of companies personally liable for harmful content on their platform, will ensure internet firms meet their responsibilities.

“The era of self-regulation for online companies is over,” culture secretary Jeremy Wright said. 

Culture Secretary Jeremy Wright has called for compromise in Brexit talks between Labour and the government.

He told the Today programme: "I think we have to move forward... We must make sure we're all prepared to compromise to fulfil that primary objective.

"What everyone has agreed is that we should sit down and talk sensibly about how we fulfil that objective.

"There's some urgency to it but I do think it's important for everyone to take their responsibilities seriously, whatever party they come from, and try and get to a point where we leave the EU, as people have said they wish to do, and to do it on the best possible terms.

"I think that's achievable. I would prefer we did it on the basis of the PM's deal... But if we can't do that then let's find another way forward."

A customs union with the European Union is the "most likely outcome" of talks between Theresa May and Jeremy Corbyn, a government minister has admitted.

In remarks that risk further inflaming tensions in the Conservative Party, the solicitor general Robert Buckland insisted his party needed "to compromise" to salvage Brexit.

Labour's key demand is for a customs union with Brussels, but Brexiteers vehemently oppose anything that would restrict the UK's ability to strike independent free trade deals post-Brexit.

Labour leader Jeremy Corbyn has taken a moment away from the Brexit chaos to send gardening tips to US Congress' rising star Alexandria Ocasio-Cortez. Mr Corbyn is mad on his allotment, and had some advice for the American politician.

Conservative ministers vying to succeed Theresa May have sought to boost their credentials by urging the party to do more to appeal to young people.

Seven cabinet ministers widely believed to be planning leadership bids are among more than 40 MPs who have endorsed a new report calling for the Conservatives to move to the centre ground to win over younger voters.

The report, by think-tank Onward, says there are 3 million voters under the age of 35 who would consider voting Conservative if the party adopted a more moderate agenda.
