Boris Johnson could be forced to correct any false claims he makes in the House of Commons.
According to HuffPost, Commons Speaker Lindsay Hoyle has backed calls for the Commons Procedure Committee to examine "how perceived inaccuracies could be corrected" as soon as possible.
It comes after a string of occasions where the Prime Minister has made incorrect or false statements, and refused to correct the record after they have been debunked.
Most recently, in the commons today, he accused Keir Starmer of opposing his Brexit bill - which is untrue.
The PM claimed: "Last night, our friends in the EU voted to approve our Brexit deal, which he opposed."
In fact, despite resistance from his backbenchers, Mr Starmer whipped his MPs to vote in favour of the deal, in a vote on December 30 2020.
And last month Mr Johnson claimed Labour had voted against a 2.1% pay rise for nurses, which they had not.

On each occasion, the PM's spokesman and press secretary were asked if he would correct the record - and they said he would not.
Today, Mr Johnson's press secretary claimed the PM had been referring to Mr Starmer having backed a second referendum, which transcripts demonstrate he was not.
A spokesman for Mr Starmer said: "Unfortunately there is a pattern of behaviour with the PM, which at the very least is not being totally straight. If not dishonest, it's a colourful misrepresentation of the truth."
It's understood Speaker Hoyle held a meeting with six opposition MPs today, and backed the suggestion of updating the rules on correcting inaccuracies.
A spokesperson for the Speaker's office told HuffPost: "Mr Speaker welcomed the meeting and the proposal to ask the Procedure Committee to look into how perceived inaccuracies could be corrected.
“He hoped such a measure would improve transparency in House of Commons proceedings.”
And the Procedure committee said: "The committee will consider any request it receives to look at the matter of ministerial corrections in the new session of parliament.”
