Sir Philip Green says he is 'sad and sorry' for BHS workers as he condemns report into retailer's collapse

Sir Philip Green said he is trying to find a "solution" for the BHS pension fund as he expressed his sadness for the firm's workers caught up in the "horrid story".

He admitted selling the chain to Dominic Chappell's Retail Acquisitions firm was "a very bad choice", and has since felt "badly let down".

But he slammed the parliamentary committees who produced a scathing report into his actions, insisting it was a "predetermined and inaccurate output of a biased and unfair process".

Amid growing calls for Green to be stripped of his knighthood, Downing Street said the report was "clearly concerning" and Prime Minister Theresa May would "lean lessons for the future".

Green was branded the "unacceptable face of capitalism" and accused of extracting large sums from BHS, leaving the business on "life support".

The two committees - Work and Pensions and Business, Innovation and Skills - said Green had a "moral duty" to make a "large financial contribution" to the 20,000 pensioners facing substantial cuts to their benefits.

Meanwhile, Sir Green has demanded an immediate apology from the chairman of the Work and Pensions Committee, Frank Field MP.

Speaking on BBC Radio 4's Today programme, MP Field compared Sir Green unfavorably to late media mogul Robert Maxwell, who took millions from the Mirror Group's pension fund.

In the complaint, law firm Schillings said: "You alleged that our client had stolen money, specifically from the BHS and Arcadia pension fund. This statement is highly defamatory and completely false.

"Our client has never stolen any money from BHS, Arcadia or the pension funds and you know that.

"In particular, there is nothing in the recent Report of the Work and Pensions and Business, Innovation and Skills Committees, (the Report) (of which you were one of the Chairs) to support your allegation".
