MPs have again rejected Boris Johnson’s calls for a snap election, as the five-week suspension of Parliament begins.
In all, 293 MPs voted for the prime minister’s motion for an early poll, far short of the number needed.
Earlier, opposition MPs confirmed they would not support an October poll, insisting a law blocking a no-deal Brexit must be implemented first.
Parliament was officially suspended – or prorogued – just before 02:00 BST on Tuesday and will reopen on 14 October.
A group of Labour backbenchers protested against the move, appearing to try to block Speaker John Bercow amid raucous scenes in the House of Commons.
Signs saying “silenced” were held up by the group in front of Mr Bercow – who earlier announced his resignation – just as he was due to lead MPs in a procession to the House of Lords to mark the suspension of Parliament.
MPs approved, without a vote, a motion from Labour leader Jeremy Corbyn demanding the government abide by the rule of law.
‘Strive to get an agreement’
At present, UK law states that the country will leave the EU on 31 October, regardless of whether a withdrawal deal has been agreed with Brussels or not.
But new legislation, which was granted royal assent on Monday, changes that, and will force the PM to seek a delay to 31 January 2020 unless a deal – or a no-deal exit – is approved by MPs by 19 October.
BBC political editor Laura Kuenssberg said although No 10 insisted it was not looking to break the new law, efforts were under way to examine ways of getting around it.
The prime minister said the government would use the time Parliament was suspended to press on with negotiating a deal with the EU, while “preparing to leave without one”.
“No matter how many devices this Parliament invents to tie my hands, I will strive to get an agreement in the national interest,” he said.
“This government will not delay Brexit any further.”
But he was warned that ignoring the new law could prompt a legal challenge while ministers called it “lousy” and said they would “test to the limit” what it required of them.
Mr Johnson told MPs that Labour leader Jeremy Corbyn had previously said he would back an election if legislation to prevent the government from forcing through a no-deal Brexit on 31 October became law.
“By his own logic, he must now back an election.”
But Mr Corbyn told MPs that Labour was “eager for an election – but as keen as we are, we are not prepared to risk inflicting the disaster of no-deal on our communities, our jobs, our services, or indeed our rights”.
And he said the prime minister was suspending Parliament to avoid discussions of his plans.
Labour, the SNP, the Liberal Democrats, the Green Party, the Independent Group for Change and Plaid Cymru met on Monday morning and agreed not to back the motion for an election.
