The front pages of Sunday's papers are starting to emerge, starting with the Mirror, which claims Brexit "might never happen".

A look ahead to a morning of major political interviews.

Andrew Marr's guests include Conservative MP Dominic Raab, who was Brexit secretary until last Thursday, when he quit the cabinet over what he called "fatal flaws" in the draft Brexit agreement.

Also on the show are shadow attorney general Baroness Chakrabarti and Scotland's First Minister Nicola Sturgeon.

Over on Sky News, Sophy Ridge speaks to both Prime Minister Theresa May and Labour leader Jeremy Corbyn.

John Pienaar will speak to Sir Graham Brady, chairman of the 1922 Committee of backbench Tory MPs - the man that all those letters of no confidence in Theresa May have been addressed to.

Also on Pienaar's Politics on BBC Radio 5 live are Education Secretary Damian Hinds and shadow transport secretary Andy McDonald.

A quick recap of some of the main developments today:

• There is "still the potential to improve" the draft Brexit deal, according to Commons leader Andrea Leadsom
• Mrs Leadsom is believed to be co-ordinating a "gang of five" Brexit-supporting cabinet ministers, inlcuding Michael Gove, Liam Fox, Penny Mordaunt and Chris Grayling - but insists she is not "a plotter"
• More than 20 MPs have sent letters of no confidence in the prime minister to Sir Graham Brady, the chairman of the 1922 Committee of backbench Conservative MPs - 48 are needed to trigger a leadership contest
• Scottish Secretary David Mundell said the PM faced an "unprecedented onslaught" and she had his support - while Environment Minister Thérèse Coffey said Mrs May would win a confidence vote "convincingly"
• Another minister, Alistair Burt, warned what he called "purist Brexiteers" that the "consensus on accepting the result of the referendum by Remain-voting MPs" could break down and Parliament will not support a "no deal" Brexit
• Shadow chancellor John McDonnell said "if the government aren't willing to get a constructive deal, let's have a general election" adding that the option of another referendum was still "on the table"

The document , externalthat sparked ministerial resignations and letters of no confidence in the prime minister sets out how the UK leaves the European Union, scheduled for 29 March 2019.

It's 585 pages long but fortunately Chris Morris, from BBC Reality Check, has pulled out the key points and what they mean.

Irish PM Leo Varadkar insists that his government has had "no hidden agenda" during the Brexit negotiations - and had been clear that it wanted "no hard border" on the island of Ireland.

Addressing a conference of his ruling Fine Gael party, Mr Varadkar said: "Our only red line has ever been to protect the Good Friday Agreement and all that that means."

Party members applauded when he told them: "Let's seal the deal and let's get on to the next phase, which is managing the transition period and negotiating a new, deep and close relationship with the United Kingdom."

The draft withdrawal deal includes an agreement on the Irish border.

Both sides want to avoid a "hard border" - physical checks or infrastructure between Northern Ireland and Ireland - but until now had been unable to agree how.

A key part of the negotiation has been the controversial border "backstop".

But what is it?

Theresa May would win a vote of no confidence "very convincingly" says Environment Minister Thérèse Coffey.

Following up her appearance on PM with an interview on the BBC News Channel, Ms Coffey says she's "confident the prime minister has delivered" on the result of the referendum.

"The withdrawal agreement is only temporary", she insists. And the so-called "backstop" will not need to be used if a trade deal is struck by the end of 2020.

Asked who would replace Mrs May if she is forced out, Ms Coffey refuses to speculate.

"I think we are getting ahead of ourselves," she says.

Conservative MP Crispin Blunt has told the BBC that whoever the prime minister is over the next few months is going to face exactly the same circumstances, as "the Commons will say no to the deal."

He says that over the weeks to come, people will see that the deal the EU has offered the UK is "simply infinitely worse" than the option of "moving to a clean global Brexit with WTO terms".

Mr Blunt did not make it clear whether he had written a letter to Sir Graham Grady, arguing that "it doesn't matter who the leader is, as the Commons won't vote the withdrawal agreement through regardless".

He thinks that leaving without a deal would mean "we will have a lot of money, will be able to make fee trade deals and we will have the freedom to manage the economy in our best interests".

He adds that it would be "criminal" if the UK does not grasp this "fantastic opportunity", but notes that it comes with its challenges.

Conservative Lord Lilley adds that while Theresa May has "shown an extraordinary degree of mental and resilience" she has "deployed it in the wrong way".

Lord Lilley says a vote of confidence would not trigger a general election, and says "it's less likely she'll be defeated, but when there's a large number against her it will become clear that she can't get this deal through and she and this government will have to think again".

He says Theresa May "should go", likening the situation to when Churchill replaced Chamberlain in World War Two "to get the best outcome".

"Theresa May is every bit as nice as Neville Chamberlain, but we need somebody to get us a better and more attractive deal," he adds.

Conservative peer and veteran Eurosceptic Lord Lilley says this week has been "a huge shock" as "there's such a difference between the plan she's come back with and what she was promising".

"She's promised a hundred times that we'd leave the customs union and the single market, and this keeps us in and gives us no right to leave," he adds.

Lord Lilley says he had been trying to discourage people from handing in letters against May "but I'm afraid I can't do that anymore".

"If I was in the House of Commons, I'd put in a letter myself."

Lord Lilley says Theresa May "has come to believe her own rhetoric that a no deal is a bad thing", and that the UK is in a "strange position where we have to ask permission to leave".

He adds that countries won't be able to discriminate against the UK on WTO terms.

Lord Lilley says "there will be lots of people who have written letters but not made it public" and although this surge towards a vote of no confidence has come at "a bad time", he adds that it "wont wreck the Conservative Party".

Speaking on BBC Radio 4's PM programme, Conservative MP Thérèse Coffey says Theresa May's draft withdrawal agreement offers a "smooth orderly exit, a transition period, and the level of detail you would expect".

She says the draft Brexit plan is "what businesses are looking for" and that she is "confident that when people get into the full detail and what that actually means, many more will endorse it".

Thérèse Coffey says Theresa May has done "a great job with her team to get us where she has" and calls for MPs to support the prime minister and her plan.

The transition period refers to a period of time after March 2019, when the UK leaves the EU, to allow time to hammer out the details of the future relationship and also then smooth the way to those new rules, for businesses and others.

Andrea Leadsom says she plans to "work very hard to deliver the Brexit 17.4 million people voted for".

The Leader of the House of Commons says "there's still the potential to improve on the clarification of the measures" within the deal and that's what she's hoping to help with.

When questioned on her pizza eating, Mrs Leadsom jokes she'd be "having to exercise a lot".

"I wouldn't describe myself as a plotter," she adds.

When asked if she's happy with the deal, Andrea Leadsom says "the UK cannot be trapped in a permanent customs arrangement" and it's "really important that we get some clarity and improvement on that particular aspect of it".

When they didn’t jump ship over Theresa May’s Brexit deal you might have thought that meant these key Brexiteers in her Cabinet were ready to toe the line in a show of what’s supposed to be known as “collective responsibility”.

But the fact that they’re still manoeuvring to change the details of Theresa May’s deal (while declaring their support for her), is yet another sign of the extraordinary political times we are in. But this apparent 'gang of five' inside the cabinet differ in their priorities.

The Leader of the House Andrea Leadsom - who’s understood to be leading them - doesn’t want Britain to be trapped in an endless backstop, and wants technological solutions to get around it.

Environment Secretary Michael Gove is worried about treating Northern Ireland differently from the rest of the UK. The group is at an “embryonic” stage but will they get their tweaks?

Andrea Leadsom thinks there’s “still more to be done” and that they “do still have more time” before the EU Council at the end of the month.

But that leaves only just over a week - and the EU doesn’t look to be in the market for renegotiation at the moment.

Former Labour leader Gordon Brown has suggested the creation of a "representative panel" in every region which can engage in dialogue with "informed advocates from both sides" to see if "any common ground" can be found, could be the solution to forming a Brexit plan that unites the country.

In a letter published today, Gordon Brown says he "does not propose a rerun of the arguments of the last election", but hopes the "panels of a few hundred citizens" could focus on contentious issues where the situation has significantly changed since 2016.

He notes that "nothing in the near 600-page Brexit documents gives any long-term certainty".

"The deadlock in Parliament seems unlikely to be broken by MPs alone," he says, and notes "there is a danger that the next two years will simply be a run of the last two".

Mr Brown says "far more will have to be done" if the "now bitterly divided country" is to unite, and warns that "the divisions could continue to worsen as at least two and possibly many more years" of EU negotiations lie ahead.
