Keith Vaz will face MPs on the Home Affairs committee to discuss his future as its chairman after becoming embroiled in a scandal involving male escorts.
The Labour MP, who is under pressure to quit as chairman, is facing a possible investigation by Commons' sleaze watchdogs as the fallout from reports that he paid two male escorts for their services threatens to overwhelm his career.
The high-profile Leicester East MP returned to work in the House of Commons on Monday and remained composed as he asked questions in the chamber about terror suspects who have fled Britain to join so-called Islamic State as well as the war in Yemen, where he was born.
The 59-year-old, who was first elected in 1987, has publicly apologised to his wife and children for the "hurt and distress" he caused them.
Mr Vaz met the escorts at a flat he owns near his family home in north London last month, according to reports in the Sunday Mirror.
It also claimed that money was paid into an account used by one of the escorts by a man linked to a charity set up by the MP.
There is no suggestion in the newspaper report that the charity's money was used in the affair.
Labour leader Jeremy Corbyn indicated there was no need for Mr Vaz to stand down from the party, stating: "Well, he hasn't committed any crime that I know of. As far as I'm aware it is a private matter, and I will obviously be talking to Keith."
