Theresa May’s Brexit withdrawal bill will not be published or debated until early June, the government says.
The prime minister is continuing to face pressure from her own MPs to resign following her pledge of a “new deal” on Brexit.
It comes after Commons leader Andrea Leadsom stepped down on Wednesday night over the PM’s Brexit policy.
Downing Street has announced she will be replaced by Treasury minister Mel Stride.
Several cabinet ministers have told the BBC that Mrs May cannot stay in her post.
Standing in for Mrs Leadsom, Mark Spencer told the Commons: “We will update the House on the publication and introduction of the Withdrawal Agreement Bill on our return from the Whitsun recess.”
He added that the government planned to publish the bill in the first week of June.
“We had hoped to hold second reading on Friday 7 June,” he added.
“At the moment, we have not secured agreement to this in the usual channels. Of course we will update the House when we return from recess.”
On Wednesday, Theresa May told the Commons that the legislation would be published on Friday.
Second reading is when MPs get a first chance to debate legislation, before deciding whether it should proceed to detailed scrutiny.
Hunt on Trump visit
Earlier, Foreign Secretary Jeremy Hunt said she would still be PM when President Trump visits the UK in early June.
Responding to a question after a speech at the National Cyber Security Centre, he said: “Theresa May will be prime minister to welcome him and rightly so.”
It is possible for Mrs May to quit as Conservative leader before Mr Trump’s visit, but continue as prime minister on a caretaker basis.
The US president is due to make a three-day state visit to the UK from 3 to 5 June.
