Former BHS owner Dominic Chappell has been asked for millions of pounds from the Pensions Regulator to cover the collapsed retailer’s deficit, according to reports.

Chappell and his firm Retail Acquistions, which owned BHS before it fell into administration in April, has been sent warning notices by the regulator saying it wants “multiples of £1m”, The Guardian reported.

The regulator is also chasing the other former owner, Sir Philip Green, over the chain’s £571m pension deficit. Green sold BHS to multiple bankrupt Chappell for £1 last year.

The regulator is reportedly seeking around £300m from Green. 

Last week, the regulator launched enforcement action against Green and Chappell over their failure to agree a deal on the deficit.

MPs last month backed calls for Green to be stripped of his knighthood over his part in the collapse of BHS. However any final decision will come from the the Honours Forfeiture Committee.
