17.00 - MPs vote on Bill to block no deal
MPs are now voting on the second reading of a Bill, which would force the Prime Minister to delay Brexit by three months if no deal with the EU is agreed by October 19.

If the legislation passes, the government has vowed to push for a vote on a snap general election.
15.15 - MPs opposed to no deal bring Bill to Commons
MPs opposed to a no-deal Brexit are introducing legislation to the Commons which would force the Prime Minister to delay the UK's departure by three months if no deal with the EU is agreed.
Introducing the EU Withdrawal No. 6 Bill, Labour MP Hilary Benn said: "I think wherever we stand on this issue, we know there is very little time left and, following the decision on prorogation, there is even less time than would have been available previously."
The Leeds Central MP appealed to MPs to "treat each other with respect" during the debate.
He said the Bill has "wide cross-party support", including from former senior Cabinet members.
Mr Benn added: "You could describe it as a somewhat unlikely alliance, but what unites us is a conviction that there is no mandate for no deal, and that the consequences for the economy and for our country would be highly damaging."
15.00 – Ed Vaizey says he learnt about risks of being ousted on Twitter
WATCH: Ed Vaizey reveals how he found out he could be ousted
Former Conservative MP Ed Vaizey said he was not personally warned he risked being barred from the party for voting against the government yesterday.
He was among 21 Tory rebels ousted from the party, meaning they cannot stand for the Conservative Party at a general election.
“It was delivered on Twitter, through journalists saying that this is what the government was planning to do. No one ever said it to my face,” he told talkRADIO’s Matthew Wright.
“I thought can I look myself in the mirror on Wednesday morning knowing that I voted with the government and people far more braver than me, who’ve been fighting this battle far harder than I have, have lost the whip.”
14.30 - Rory Stewart retains support of local Conservatives
The president of Rory Stewart’s constituency said he will continue to support his MP despite him being barred from the party.
Robert Craig said he supported Mr Stewart’s decision to vote against the government, and he expected Conservative Campaign Headquarters (CCHQ) to send through a list of alternative candidates.
“If we decide, as I would expect we will, to back Rory, I think CCHQ are basically going to have to dissolve us,” he said.
“It would be tragic to lose someone of Rory's intellect and standing from politics at exactly the wrong time.”
Meanwhile, the chairman of the Welsh Conservatives, Byron Davies, said he supported the Prime Minister for ousting rebel MP Guto Bebb.
“Guto has chosen his path in this and there's nothing we can do about that. Naturally we are disappointed that he is not supporting the Prime Minister,” he said.
12.00 - Boris Johnson undertakes first Prime Minister's Questions
Boris Johnson is being questioned in the House of Commons for the first time in his role as Prime Minister.
It comes during a tumultuous time in politics, with Mr Johnson announcing last week that he will suspend Parliament, which caused rifts in the party.
11.45 - Guy Verhofstadt slams Conservative Party
EU negotiator Guy Verhofstadt has criticised Boris Johnson after he expelled Sir Winston Churchill’s grandson from the party.
Nicholas Soames was one of the 21 Tory MPs who voted against the government and was expelled from the party.
Mr Verhofstadt tweeted: “Sir Winston Churchill was a founding father of the European Union, convinced that only a united Europe could guarantee peace. He would surely be stunned about the state of today's Conservative Party.”
11.00 - Boris Johnson's parliamentary suspension clears legal hurdle
A judge at the highest court in Scotland has found Boris Johnson’s planned prorogation of Parliament is lawful.
Anti-Brexit activists had said the Prime Minister’s plan to suspend Parliament ahead of a Queen’s Speech on October 14 was a move to limit scrutiny from MPs.
However, Judge Lord Doherty said the decision to suspend Parliament was for politicians and not the courts.
“This is political territory and decision-making, which cannot be measured by legal standards, but only by political judgements,” he said.
10.00 - Rory Stewart lays in to Conservative Party
Rory Stewart has called negotiations between the European Union and Boris Johnson’s government a “sham” and dubbed no-deal Brexit a “fairy story”.
He said it has been clear “for months” there was no majority for no deal and “no amount of threats or thinking can make it otherwise”.
He tweeted: “No deal is an [sic] fairy-story - rejected repeatedly by Parliament and by the majority of voters. Prorogation and purges are undermining our democracy in pursuit of an ill-judged, poorly executed, and deeply damaging fantasy.”
Mr Stewart revealed he was told of his removal from the Conservative Party by text message, after he was one of 21 Tory MPs who voted against the government yesterday.
Meanwhile, Scotland’s First Minister Nicola Sturgeon has urged the Prime Minister to support an opposition motion today that would prevent a no-deal Brexit.
She tweeted: “If he has any respect for democracy, Johnson will support this amendment, agree to abide by will of Parliament on the Bill blocking 'no deal' and then submit to the verdict of the people in a general election.”
09.00 - Ministers silent as they arrive for Cabinet meeting
Ministers have begun arriving for a Cabinet meeting ahead of a parliamentary vote on an opposition Bill to prevent a no-deal Brexit.
Conservative Party chairman James Cleverly, Foreign Secretary Dominic Raab and Leader of the House of Commons Jacob Rees-Mogg declined to answer questions as they entered Number 10.
Ahead of the days’ proceedings Boris Johnson tweeted: “Corbyn and his surrender bill would mean years of uncertainty and delay. I am determined to lead this country forward and take Britain out of the EU on October 31st.”
Business minister Kwasi Kwarteng has defended the Prime Minister's decision to expel rebel MPs who voted against the government yesterday.
“It was very clearly stated that Conservative MPs would lose the whip. Now 21 of them out of 312 - that is about six per cent - chose to vote against the Government and they had the whip withdrawn,” he said.
“I think it is a shame - a lot of them are very talented people. But you cannot have people standing as Conservative MPs when they are against the Government's policy on the key issue of the day.”
