Conservative immigration minister Robert Goodwill will face a grilling from the powerful Home Affairs Committee this afternoon, after the group's chair Keith Vaz is expected to resign from the top job.

The Labour MP, who has been chair of the influential group since 2007, has faced allegations of soliciting sex with male escorts.

Vaz, 59, has apologised to his wife and two children over The Sunday Mirror sting and referred the claims to his solicitor.

"At this time I do not want there to be any distraction from the important work the Home Affairs Select Committee undertakes so well," he said in a statement. "Select committees do vital work in holding the government and others to account.

"We are due to publish two reports, one into anti-Semitism and the other into FGM (female genital mutilation) in the next few days, in addition we have a number of key witnesses.

The Leicester East MP is expected to stand aside as chair of the Home Affairs Committee when they meet privately at 2pm BST on Tuesday afternoon.

The group will then hold an evidence session with Goodwill and Sarah Rapson, the director general of the UK Visas and Immigration Directorate, from 3.30pm. The committee is scheduled to question new Home Secretary Amber Rudd tomorrow.
