Bangla sanglap desk: Parliament will be suspended just days after MPs return to work in September – and only a few weeks before the Brexit deadline.
Boris Johnson said a Queen’s Speech would take place after the suspension, on 14 October, to outline his “very exciting agenda”.
But it means the time MPs have to pass laws to stop a no-deal Brexit on 31 October would be cut.
House of Commons Speaker John Bercow said it was a “constitutional outrage”.
The Speaker, who does not traditionally comment on political announcements, continued: “However it is dressed up, it is blindingly obvious that the purpose of [suspending Parliament] now would be to stop [MPs] debating Brexit and performing its duty in shaping a course for the country.”
Labour leader Jeremy Corbyn said: “Suspending Parliament is not acceptable, it is not on. What the prime minister is doing is a smash and grab on our democracy to force through a no deal,” he said.
He said when MPs return to the Commons next Tuesday, “the first thing we’ll do is attempt legislation to prevent what [the PM] is doing”, followed by a vote of no confidence “at some point”.
Hundreds of protesters gathered in Westminster on Wednesday evening chanting “stop the coup” and carrying anti-Brexit placards and EU flags.
The demonstration, which was organised hours beforehand, started outside Parliament before spreading towards Downing Street.
At the scene, BBC correspondent Richard Galpin described the atmosphere as peaceful and lively.
He said “good-natured” protesters on College Green broke through barriers which had been in place to separate live TV crews from members of the public – before traffic on Parliament Square was blocked by some people who sat down in the road.
Several protesters he spoke to indicated this was only the beginning of the disruption, with more demonstrations being organised for the weekend.
Three Conservative members of the Queen’s Privy Council took the request to suspend Parliament to the monarch’s Scottish residence in Balmoral on Wednesday morning on behalf of the prime minister.
It has now been approved, allowing the government to suspend Parliament no earlier than Monday 9 September and no later than Thursday 12 September, until Monday 14 October.
Leader of the House Jacob Rees-Mogg, who was at the meeting with the Queen, said the move was a “completely proper constitutional procedure.”
Earlier, Mr Johnson said suggestions the suspension was motivated by a desire to force through a no deal were “completely untrue”.
He said he did not want to wait until after Brexit “before getting on with our plans to take this country forward”, and insisted there would still be “ample time” for MPs to debate the UK’s departure.
“We need new legislation. We’ve got to be bringing forward new and important bills and that’s why we are going to have a Queen’s Speech,” Mr Johnson added.
Legal precedent and challenge
Shutting down Parliament – known as prorogation – happens after the prime minister advises the Queen to do it.
The decision to do it now is highly controversial because opponents say it would stop MPs being able to play their full democratic part in the Brexit process.
A number of high profile figures, including former Prime Minister John Major, have threatened to go to the courts to stop it, and a legal challenge led by the SNP’s justice spokeswoman, Joanna Cherry, is already working its way through the Scottish courts.
After the announcement, Sir John said he had “no doubt” Mr Johnson’s motive was to “bypass a sovereign Parliament that opposes his policy on Brexit”, and he would continue to seek legal advice.
BBC royal correspondent Jonny Dymond said it was established precedent to prorogue Parliament before a Queen’s Speech, albeit generally more briefly, and rarely, if ever, at such a constitutionally charged time.
He said it was “Her Majesty’s Government” in name only and it was her role to take the advice of her ministers, so she would prorogue Parliament if asked to.
It is not possible to mount a legal challenge to the Queen’s exercise of her personal prerogative powers.
But anti-Brexit campaigner Gina Miller – who previously won a legal battle against ministers over Article 50 – has made a judicial review application to the courts about Mr Johnson’s decision.
She told the BBC’s Clive Coleman: “If the intention of using this prorogation – and the effect – is that it limits Parliament sovereignty, then we believe that’s illegal and unconstitutional.” Ref: BBC
