Lord Alan Sugar has dubbed the Government sell-off of Royal Mail a "bargain basement sale" and demanded an inquiry to find out who benefited from it.
The businessman and Labour peer made his comments during question time in the House of Lords as Government business spokesman Lord Popat said banks who helped with the sale could receive up to £18.4 million in fees.
The Government has faced widespread criticism that it under-valued the company after Royal Mail shares soared from the offer price of 330p to more than £5 during the first few days of trading.
Lord Popat said the key objective had been to "secure value for money for the taxpayer".
The Apprentice winner in 2010, Stella English, says she does not regret taking part in the BBC 1 show, despite losing her recent constructive dismissal claim against Lord Sugar and his company, she told Daybreak.
English claimed she was forced to resign from the £100,000 a year job that was her prize for winning series six of the show because "it was not a role of substance". But the claim was dismissed by the tribunal panel which ruled the case "should never have been brought".
Last week Lord Sugar launched a counter claim against Ms English but an East London Tribunal Service panel ruled the mother-of-two should not have to repay legal costs.
Alan Sugar has launched a counter-claim against former Apprentice winner Stella English.
Now Sugar has initiated proceedings to try to recoup some of the legal fees he paid.
Lord Sugar has vowed to take on the claim culture as a "personal crusade" after former winner of The Apprentice Stella English lost her constructive dismissal case against him.
Speaking to ITV News he said the case was "tantamount to blackmail", saying he hoped other businesses would fight similar cases.
Lord Sugar said in a statement that Stella English's claim was "a derisory attempt to smear [his] name" and her reputation "is now in tatters".
A judiciary paper said Stella English's had been dismissed:
The judges also ruled that the claim "should never have been brought."
Former winner of The Apprentice Stella English has lost her claim of constructive dismissal against businessman Lord Sugar, the Judicial Office said.
Lord Sugar said he feels "wronged" by a former winner of the Apprentice who is currently suing him for constructive dismissal, an employment tribunal heard today.
Stella English, 34, from Whitstable, Kent, claims she was treated as an "overpaid lackey" after winning series six of the BBC1 programme.
Giving legal submissions today, Lord Sugar's representative Seamus Sweeney said: "The claimant has, in the eyes of Lord Sugar, deliberately courted the media with a view of damaging his reputation."
He told how Ms English had "sold her story" to the press several times and accused her of being a "headline-grabber", deliberately sensationalising aspects of her evidence.
He told the tribunal the same was true of Ms English, adding: "Using the media, in this case, was a weapon of choice... It was a first weapon of choice."
Stella English arrived at East London Tribunal Courts this morning. The employment tribunal involving Lord Sugar and the winner of 2010's The Apprentice, is expected to conclude today.
