Brexit vote result - LIVE: Jeremy Corbyn tables vote of no confidence in Theresa May that could bring down government after historic 230-vote Commons defeat

The government had indicated it could support three amendments. John Bercow has declined to call a vote on any of them.

It means MPs will not be allowed to vote on motions that would have demanded a time-limit on the Northern Ireland backstop - something No 10 hoped would give it fresh leverage to secure further concessions with Brussels. 

Two of the amendments ministers might have backed would have done this, but neither was chosen by Mr Bercow.

Instead, MPs will vote on motions that insist the UK must be able to leave the backstop without the approval of the EU.

Geoffrey Cox, the attorney general, is opening the last day of the Brexit debate in the Commons.

He says of the government's Brexit deal:

"It settles the bills, it legally allows for the orderly completion of these thousands of continuing transactions, of judicial proceedings, accounting procedures, that otherwise would be thrown into a legal void.

"And it provides for a period of adjustment, for people and for businesses, of the next 21 months, extendable up to two years, to allow our businesses and our individual citizens to adapt to the new realities."

Asking MPs if they want to "opt for order or chaos", he tells critics:

"What are you playing at? What are you doing? You are not children in the playground, you are legislators."

STORY: MPs will be given a vote on the UK's "right to terminate" the Northern Ireland backstop without the EU's approval

Geoffrey Cox says any orderly exit from the EU requires a withdrawal agreement and that no alternative option being discussed would negate the need for a backstop.

He tells MPs:

"Whatever solution may be fashioned, if this motion were defeated and this deal defeated, this withdrawal agreement will have to return in much the same form with much the same content, and therefore there is no serious or credible objection that has been advanced by any party to the withdrawal agreement."

In the Commons chamber, government chief whip Julian Smith has just called his opposite number, Labour's Nick Brown, outside for a chat. 

Seconds earlier Mr Smith had been deep in a whispered conversation with Theresa May...

Geoffrey Cox dismisses the amendment tabled by Tory backbencher Sir Edward Leigh, which says the UK should leave the backstop unilaterally if it becomes permanent.

The attorney general says the motion "is one that would, in my judgement, not be compatible with our international law obligations". 

If passed, the motion "would likely not be seen by the European Union as ratification, and certainly would raise serious question marks over it", he adds.

Campaigners calling for a fresh Brexit referendum have built a mock Titanic showing Theresa May heading for an iceberg. Here is the so-called HMS Brexit in all its "glory"...

Labour has been fined £12,500 by the Electoral Commission for failing to accurately report donations.

The watchdog's director of regulation, Louise Edwards, said: 

"As a well-funded political party it should be able to meet its legal requirements.

"The reporting requirements are clear, so it is always disappointing when parties and campaigners fail to comply.

"The law clearly states when and how financial data is required to be submitted to the commission.

"We will continue to enforce these requirements on all parties and campaigners to ensure voters have the information they need."
