MPs to return to parliament tomorrow morning after Boris Johnson's suspension ruled illegal, Speaker John Bercow says

Prime minister's questions will not take place, but MPs will be able to question ministers and table emergency motions

The House of Commons is to sit on Wednesday at 11.30, with "full scope for urgent questions, ministerial statements and applications for emergency debates", Commons Speaker John Bercow has announced.

There will be no half-hour session of questions to the prime minister, as is normally part of the Commons routine on Wednesdays.

MPs began returning to Westminster even before the announcement was made, with one Labour MP issuing a demand for "Liar Johnson" to turn up to be grilled in the Commons.

Meanwhile the Speaker of the Lords, Lord Fowler, announced that the Upper House will sit from 3pm on Wednesday and 11am on Thursday.

Speaking outside parliament, Mr Bercow stressed that parliament was not being recalled, as the Supreme Court's ruling that Boris Johnson's prorogation was unlawful means that the suspension of sittings two weeks ago is void.

Mr Bercow said: "The citizens of the UK are entitled to expect that parliament does discharge its core functions. That it is in a position to scrutinise the executive, to hold ministers to account, and to legislate if it chooses.

"In the light of that explicit judgement I have instructed the House authorities to prepare not for the recall - the prorogation was unlawful and is void - but for the resumption of the business of the House of Commons.

"Specifically, I have instructed the House of Commons staff to undertake such steps as are necessary to ensure that the House of Commons sits tomorrow and that it does so at 11.30am.

"I have contacted party leaders - or where that has not been possible senior representatives of the political parties - in order to inform them of my thinking and to prepare the way for the House of Commons to do its work.

"Owing to notification requirements, it will not be possible for there to be a prime minister's questions, but for the avoidance of doubt there will be full scope for urgent questions, ministerial statements and applications for emergency debates."

Even before any announcement on when proceedings will resume in the House of Commons, MPs including Liberal Democrat leader Jo Swinson declared that they were returning to Westminster.

The Conservative chair of the House of Commons Foreign Affairs Committee, Tom Tugendhat issued a photo of himself in the Commons chamber, with the simple message: “We’re sitting.”

Labour MP Stephen Doughty, a prominent opponent of Brexit posted a picture on social media of himself in the back of a taxi heading from a TV studio to Westminster.

“I’m on my way back to Parliament right now,” said Mr Doughty. “The Supreme Court has ruled Parliament was never suspended and PM has acted unlawfully – so we should be back ASAP. And Liar Johnson should turn up and be held accountable for his actions.”

Responding to the court ruling, Ms Swinson said: “This confirms what we already knew – Boris Johnson isn’t fit to be prime minister. He’s misled Queen and country, and unlawfully silenced the people’s representatives.

“I’m on my way to Westminster to resume my duties in the Commons and stop Brexit altogether.”

Lord Fowler said: "The judgement of the Supreme Court today is clear - Parliament is not prorogued.

"The House of Lords performs a vital constitutional function. It holds the government of the day to account and will continue to do just that."
