Sir Lindsay Hoyle has announced there will be a vote on whether to refer Boris Johnson to the standards committee over allegedly lying to Parliament.
He told MPs: "It is not for me to police the ministerial code, I have no jurisdiction over the ministerial code even though a lot of people seem to think I have. It is not the case.
"Secondly, it is not for me to determine whether or not the Prime Minister has committed a contempt. My role is to decide whether there is an arguable case to be examined.
"Having considered the issue, having taken advice from the clerks of the House, I've decided that this is a matter that I should allow the precedence accorded to the issue of privilege.
"Therefore, (Sir Keir Starmer) may table a motion for debate on Thursday."
"Scheduling the debate for Thursday will, I hope, give members an opportunity to consider the motion and the response to it.
"The motion will appear on Thursday's order paper to be taken after any urgent questions or statements. Hopefully there won't be any.
"I hope this is helpful to the House."
