Businessman and Apprentice star's Dover Street Market contract was secured after Mansell paid rival Concentra to put in artificially high bid, says Evening Standard

Millionaire businessman Alan Sugar fell victim to bid-rigging in 2003 during the contest to refurbish Dover Street Market in Mayfair.

According to the Evening Standard, Sugar's property firm Amsprop agreed to pay £2.9m to Mansell Construction to redevelop the property, which it bought for £3.5m. However, it has emerged that Mansell paid rival developer Concentra (formerly Durkan Pudelek) £60,000 to put in an artificially high bid that would not be accepted.

Sugar, who is the star of the reality television show The Apprentice, said: “I am very impressed and encouraged that the OFT have done such a thorough job.”

Amsprop is run by Sugar's son Daniel.
