Billionaire Sir Philip Green will finally face questions from the influential Work and Pensions Select Committee over the collapse of British Home Stores (BHS), which left 11,000 employees with uncertain futures and a pensions deficit of £571m ($809m).

Green, who is probably best known as the entrepreneur behind Top Shop and Dorothy Perkins, has faced criticism for selling BHS for £1 to Dominic Chappell in 2015.

Chappell, a former racing driver, admitted to the group of MPs that he had no retail experience and alleged that Green blocked a rescue deal from Sports Direct's Mike Ashley in April.

"[Green] went absolutely crazy, screaming and shouting down the phone that he didn't want to get involved with Ashley," Chappell claimed, when he appeared before the Work and Pensions committee.

The group of MPs, led by former Labour minister Frank Field, are expected to question Green on Chappell's allegation.

Green initially was reluctant to appear before the committee, claiming Field was biased against him and urging the veteran parliamentarian to resign as chair of the group. But the businessman released a statement on 14 June, revealing that he would appear before the MPs. "I am disappointed not to have had a reply to either of my letters sent to Frank Field," Green said.

"I did not think or believe that those conducting a parliamentary process would or should express concluded views in such a public way before I have had the chance to appear before the committee."

He added: "Having given long and hard thought to the matter however, I have decided I will attend tomorrow morning, hoping and trusting that the committee will give me a fair hearing." The Arcadia Group chairman will give evidence to the Work and Pensions Committee in Portcullis House from 9.15am BST. You can watch the session live on Parliament TV.
