Brexit news: Theresa May scrambles to save EU deal ahead of third vote after Brexiteer lawyers reject attempts to break impasse

Welcome to The Independent's politics liveblog, where we will be bringing you all the latest updates throughout the day.

It's the morning after the night before in Westminster, after MPs voted to order Theresa May to delay Brexit in a dramatic series of Commons votes.

Last night's action came on the heels of an explosive week, which saw the PM's deal rejected for a second time on Tuesday. MPs then backed a bid to try to take a no-deal Brexit off the table - amid chaotic scenes where several senior minister rebelled against the government.

Our political editor Joe Watts has an essential write-through of last night's events:

Theresa May has led the UK condemnation of the shootings in mosques in Christchurch that killed 49 people.

The prime minister expressed her "deepest condolences to the people of New Zealand after the horrifying terrorist attack in Christchurch" in the wake of the devastating attacks on Friday.

She added: "My thoughts are with all of those affected by this sickening act of violence."

Foreign secretary Jeremy Hunt said: "Our hearts go out to the people of New Zealand following the news of this terrible act in Christchurch.

"NZ is one of the most peaceful, peace-loving and generous nations in the world. Your friends in the UK stand with you today in deepest sympathy."

Labour leader Jeremy Corbyn said on Twitter: "My heart goes out to the victims of the horrific terror attack in New Zealand. We stand in solidarity with the Muslim community in Christchurch and around the world.

"We must defeat the bigotry which fuels such hatred and violence."

We are running a separate liveblog on the events in Christchurch, which you can follow here:

Back to Brexit, and David Lidington has denied that the government was falling apart after seven cabinet ministers - including Brexit secretary Steve Barclay -voted against the PM's motion on delaying exit day.

Mr Lidington, who is Ms May's de-facto deputy, told the Today programme: "It was a free vote in that division yesterday. Now, what happens this morning is that the entire cabinet has accepted the position that Parliament voted for last night.

"I've been working very constructively with Steve Barclay since his appointment a couple of months ago despite the fact that he and I were vigorously on opposite sides of the debate during the referendum, and we are continuing to work very constructively together today and in the days to come."

Mr Lidington said he believed that Leave-backing ministers had used the free vote as "an opportunity to register how unhappy they were with being in the position where we don't really have an option as a country except to seek an extension of our time in the European Union".

Mr Lidington said that leaving on March 29 with no deal remains the "legal default position" but the likelihood of it happening had "diminished" after this week's votes.

He said he was still hoping that the UK will "leave as soon as possible in an orderly fashion" by MPs backing Mrs May's Withdrawal Agreement next week.

Asked if defeat for the PM's deal might mean an extension of a year or more, Mr Lidington said: "Those are the indications which the Brussels institutions of the EU - the Commission, the Council secretariat and certain member state governments - have been giving to us."

He added: "I hope that MPs of all parties will be over this weekend just reflecting on the way forward."

On the Labour side, there were also a number of rebels. Four Labour MPs have resigned from the party's frontbench after defying Jeremy Corbyn's orders and voting against a fresh Brexit referendum.

The Labour leader had whipped his MPs to abstain on the vote but dozens broke ranks, with 24 voting for a fresh public vote and 17 voting against.

The Commons will hold a minute's silence in memory of those killed in the mosque shootings in Christchurch.

Sir Vince Cable has announced plans to stand down as leader of the Liberal Democrats, following the UK’s local elections.

“I indicated last year that once the Brexit story had moved on, and we had fought this year’s crucial local elections in 9,000 seats across England, it would be time for me to make way for a new generation,” the politician said in a statement.

“I set considerable store by having an orderly, business-like, succession unlike the power struggles in the other parties.”

Luxembourg PM Xavier Bettel does not seem very enthusiastic about the prospect of a Brexit delay. Remember - all EU27 states must approve any extension to article 50.

Dutch PM Mark Rutte - who has been an ally to May - reiterates that May's deal is the only one on the table.

EU Commissioner Phil Hogan has said the UK's no-deal tariff plans - proposals that would see no import duties levied on goods entering Northern Ireland across the border - likely breach World Trade Organisation rules.

Mr Hogan, who is commissioner for agriculture and rural development, claimed the plans unveiled by Whitehall this week were "political" and designed to "change in the news cycle from the political chaos on London".

"I think they are incompatible with WTO rules," he said of the plans, after arriving at an agriculture conference in Dublin.

Mr Hogan added: "I think the timing of it was unfortunate and it was a deliberate attempt to put Ireland more on the agenda, as if it wasn't on the agenda already."

Here's our story from when the tariff schedules were published:

A flotilla of fishing boats has set off to protest against the Prime Minister's Brexit plans.

The demonstration on the River Tyne comes the day before former Ukip leader Nigel Farage starts out on his March to Leave, from Sunderland to London.

The fishermen's organisation, Fishing For Leave, set off from North Shields, North Tyneside, up the river and headed for Newcastle's Quayside.

The flotilla made its way through the choppy waters of the Tyne, while a battered trawler was driven on the back of a lorry by road, heading for the meeting point in the city centre.

A spokesman said: "The terms of the Withdrawal Agreement are an existential threat to fishing and a total betrayal of Brexit and Britain.

"It means a second surrender of our industry and coastal communities and places a constitutional bomb under democracy."
