By 310 votes to 310, the result of the vote on the indicative votes is a tie!

Speaker John Bercow intervenes afterward to say that he will be casting his vote against the amendment - meaning it is defeated.

He says it is not for the chair to "create a majority which does not otherwise exist".

It means MPs will not be able to seize control of the parliamentary timetable on Monday to hold indicative votes on alternatives to the PM's Brexit deal.

SNP leader Nicola Sturgeon has been in Westminster today meeting Theresa May.

She says her concern is that "in the rush to reach some compromise... a bad compromise will be reached".

"People will heave a sigh of relief that an agreement has been reached but will very quickly realise it is not in the interest of UK," she says.

She also warns any agreement could be "unpicked" by a future prime minister "such as Boris Johnson".

Concerning the meeting between Theresa May and Jeremy Corbyn, Vicki Young says more discussions could take place over the weekend.

She says although the idea of the two leaders reaching a deal on Brexit seems unlikely "you can see a way where this might work".

"There could be a getting together around a customs union or workers' rights," she says.

She also says they could agree on ending freedom of movement.

"They might be in agreement - their parties are not," she adds.

Attorney General Geoffrey Cox says the government must "seek common ground" with Labour for a "swift exit".

The BBC's chief political correspondent Vicki Young says the vote taking place at the moment "is highly unusual".

"The idea that a group of backbenchers are able to dictate day after day what goes on in the House of Commons is unlike anything people have seen before," she says.

"It means that, to some extent, things are out of Theresa May's hands."

The debate in the Commons comes to an end, and MPs now begin voting.

The business motion sets aside time for the Commons to debate a bill aiming to prevent a no-deal Brexit by forcing the PM to request an extension to Article 50.

However, first MPs will vote on Hilary Benn's amendment to the motion - which sets out time for a further round of 'indicative' Brexit votes in the Commons on Monday.

Mr Cox, who has led the UK's Brexit negotiations in recent months, has suggested agreeing to some form of customs union may be a price the UK has to pay to leave swiftly.

“If we were not to leave because we were unprepared, in a situation we now face, to move any of the red lines that we have set, then it would effectively mean we never leave at all," he told the BBC.

“I don’t want to see a customs union…but if it is a choice between leaving and a customs union, then I will take leaving every single time.”

Even if the UK remained in some form of customs union, he says the UK’s sovereignty would have been hugely enhanced by Brexit.

"A customs union is not some kind of sell-out. Even if it were to be negotiated, it still involves a massive repatriation of sovereign power to this country.

“That is what the British people want to see. So we must really get that into proportion.”

And Mr Cox suggested the UK could not be bound into any customs union arrangement permanently if it deemed it to be a “straitjacket”.

“No nation is obliged to remain in an arrangement that doesn’t suit it.

“If we decided, in some considerable years' time, that we wanted to review our membership of any such customs union if we signed it - and I’m not saying we will - that’s a matter for negotiation and discussion.”

Geoffrey Cox, the government's chief law officer, has told the BBC it is a democratic necessity the UK leaves the EU and does so quickly.

The Conservatives have “signed an article of faith with the British people” over Brexit and this must be honoured, he says.

“I hope that my colleagues will see that the important prize is to leave,” he told the BBC’s Laura Kuenssberg.

“Once we are out, legally we are out…Once we have reached the open sea, we can charter our own course.”

The BBC’s political editor Laura Kuenssberg has just finished a sit-down interview with Attorney General Geoffrey Cox.

There are lots of interesting, newsworthy lines. Here’s a summary:

• Brexit is an "article of faith" for him, which must be delivered
• If the UK doesn’t drop some of its red lines, it risks never leaving at all
• The PM can no longer “rely” on Tory MPs to get any deal through
• Finding “common ground” with Labour could allow a “swift exit”
• Agreeing to a customs union would not be a “sell-out”
• The UK could not be bound into a customs union permanently

The collection of opposition parties who held a press conference earlier today said they would add an amendment to Yvette Cooper's bill - the bill which seeks to block a no-deal Brexit.

The amendment tabled by the SNP, the Independent Group, the Lib Dems, Plaid Cymru and the Green Party, states that when requesting an extension, the prime minister should “give the reason the intention of the UK to seek the approval of the people of the UK in a confirmatory public vote for any Withdrawal Agreement and Political Declaration framework for a future relationship”.

Conservative MP and Brexiteer Steve Baker responds to Chris Heaton-Harris's resignation:

Labour List's Sienna Rodgers says there is "a lot of pressure" on Jeremy Corbyn from Labour MPs who support another referendum.

"They want that to be put down as a condition of any deal," with Theresa May, she says.

"It doesn't look like that was a condition. A customs union, a close relationship with the single market, workers' rights - those are the conditions he [Jeremy Corbyn] went in with."

The BBC's Vicki Young says there are many Tory MPs who cannot countenance the PM's decision to seek a Brexit compromise with Labour.

She says there could be more resignations, as some ministers are "biding their time" to see what emerges from the talks.

Resignations from the Department for Exiting the European Union have become commonplace in the past year.

We are on our third Brexit Secretary since July 2016 (David Davis, Dominic Raab, Stephen Barclay).

And Mr Heaton-Harris has only been in his junior ministerial job since last July, when he replaced Steve Baker, who himself quit in protest at the government's strategy.

Chris Heaton-Harris has been in charge of preparations for a no-deal exit.

In his resignation letter, he says these are "well-advanced". However, he says the PM's desire not to leave the UK without a deal has made "his job irrelevant".

He said the UK should have left the EU on 29 March and he cannot support any further delay to Brexit.

The SNP's Ian Blackford says the five groups are willing to compromise and work constructively to "to find a solution that works for all of us".

But he claims "there is no such thing as a good Brexit" and the option to revoke Article 50 must be kept on the table.

The Independent Group's Chuka Umunna says he would not stand in the way of the PM's deal if it is put to a confirmatory referendum.
