Brexit news: Theresa May mocked over 'Groundhog Day' as she unveils plan B almost identical to original plan

Back in the Commons, Tory Justine Greening says parliament has "run out of road" and the only option is to offer a second referendum. She says MPs have been debating for two years and no progress is being made.

May says she believes it is possible to find a deal still and she must pursue that.

Ian Blackford, the SNP's Westminster leader, also criticises the PM for sticking to her red lines and urges her to take a no-deal Brexit off the table. If there are no pre-conditions to the talks, why is May insisting the UK must leave the EU on March 29?

Decent question from Labour's Ed Miliband too on the customs union:

Boris Johnson praises the PM for waiving the settled status fees - and for her intention to go back to the EU to seek concessions on the backstop. He asks if she will confirm that she will seek legally binding changes to the text of the withdrawal agreement?

May says she is 'exploring' with MPs what movement on the backstop would secure support from MPs. 

Nigel Dodds of the DUP also asks May to confirm that she will seek meaningful concessions from Brussels. He says there has been good engagement and willingness to seek consensus.

May says she can give him that assurance that she wants to find a way to resolve issues around the backstop.

Labour's Hilary Benn says although her door is open, 'her mind is closed'. He says she is unwilling to compromise on anything and urges her to allow a series of indicative votes.

This is a plan popular with some MPs, to allow parliament to vote on different strategies - to test what has support.

The PM says the government is tabling a neutral motion which MPs can amend. If they don't want no-deal, then they know the way to go. It will only be taken off the table by revoking article 50 and reversing Brexit or by supporting a deal.

Labour's Lucy Powell asks a similar question to Ed Miliband and other Labour MPs about whether May would allow the UK to stay in a customs union - if parliament backs it. Interesting - clearly there is something here.

May says this does not reflect the conversations she's had with colleagues.

On customs, earlier Tory grandee Ken Clarke called on May to reach out to Remainers by considering a customs union or regulatory alignment with the EU.

The Father of the House said: "Would she consider reaching out to those Remainers here who are not yet convinced of her agreement by at least relaxing, if she can't do a u-turn, her normal rejection of a customs union because I don't see those agreements with outside powers lining up to do trade agreements to compensate us for leaving Europe."

Ms May responded saying that a proposal was put forward last year which had a "degree of regulatory alignment" but that raised concern among a number of MPs - to cries of "your backbenchers" from Labour MPs.

Here's the moment Theresa May announced the decision to waive the settled status fee for EU citizens living in the UK.

Business leaders have described the PM's speech as "another bleak day" for firms.

Carolyn Fairbairn, director general of the CBI, said: "While the government's move to consult more widely is welcome, as is the commitment to scrap the settled status charge for EU citizens, the fundamentals have not changed.

"Parliament remains in deadlock while the slope to a cliff edge steepens.

"The government should accept that no-deal in March 2019 must be off the table.

"Politicians on both sides of the Commons need to step back from their increasingly entrenched positions."

Helen Dickinson, chief executive of the British Retail Consortium, said: "For all the parliamentary games over the last couple of months, we appear to be little closer to a solution, ready to be implemented before March 30, that ensures frictionless, tariff-free trade with the EU.

"While Parliament remains fractured, the retail industry is united in saying that a no-deal Brexit would be disastrous for both business and the public.

"If we want to avoid higher prices and less choice on the shelves, then Parliament must take steps to ensure we avoid a no-deal scenario at all costs."
