The Government is insisting MPs must return to Westminster - despite warnings this would turn them into "super-spreaders" of the Covid-19 coronavirus.
Cabinet Minister Jacob Rees-Mogg confirmed: "I am asking members to return to their place of work after Whitsun".
This means MPs returning to the House of Commons after the Whitsun break, which ends on June 2.
He said the Government was still encouraging everyone to work from home where they can - but Mr Rees-Mogg argued that MPs were not able to do their jobs properly via video-link, and had to attend the Commons in person to scrutinise legislation.
It comes despite a warning from Newcastle Central MP Chi Onwurah, who told the Commons that MPs would spread Covid-19 across the country.
She said: "The digital Parliament has been a huge success, but now the Leader of the House wants to abandon it and instead insists that 650 MPs - potential super-spreaders - should travel from across the country to cram into Westminster, putting constituents and staff at risk."
She suggested the Government's goal was "to cast a protective cloak around their floundering Prime Minister". It follows suggestions that Mr Johnson has struggled during the weekly session of questions to the Prime Minister without Tory MPs to cheer him on.
And she appeared to be backed by Conservative MP Michael Fabricant, who later said: "May I associate myself with the comments made earlier about 650 super-spreaders returning to Parliament?"
Blaydon MP Liz Twist said MPs - like the population in general - included people who had to stay at home for medical reasons, or had to take care of elderly relatives or children.
MPs have been allowed to take part in debates or ask questions from their own homes, using video-conferencing software Zoom.
But today, May 20, is the last say that this will be allowed.
Mr Rees-Mogg told MPs that under the current arrangements "the time this House is able to spend debating legislation faces being cut by around two thirds – I am sure all members will agree that each and every one of the 36 Bills put forward by the Government in the Queen’s Speech deserves the proper level of scrutiny.
“We have to recognise that if we persist with the present arrangement it will become harder to make progress in a timely fashion."
But MPs will not be expected to cram into a crowded Commons chamber as they have in the past, he said.
“We will not be returning to the crowded, bustling chamber of old, we will be observing social distancing."
He added: “I would finally like to reassure those members with underlying health conditions who have been told to shield or are receiving specific Government advice about their health – we are working with the House authorities to see how they can continue to contribute to proceedings within the House.”
Labour has said MPs and their staff should be allowed to continue to work from home, as per Government advice.
The spokesman for party leader Sir Keir Starmer told reporters during a telephone briefing: “The Government’s own advice, its own public health advice, is those who can work from home should.
“Parliament has developed a successful system using technology to ensure the scrutiny of Government, while allowing people to work remotely.
“The Government has yet to provide an honest explanation as to why they want to bring this virtual system to an end."
