West Ham have launched legal action against the Sunday Times and Tottenham Hotspur over allegations surrounding the Olympic Stadium bidding process.

Olympic Park Legacy Company director Dionne Knight was suspended on Friday after it emerged she was undertaking paid consultancy work for the Hammers.

West Ham released a statement on their website which said: "The newspaper's statement that Tottenham Hotspur employed the investigators who obtained private information illegally is one we are treating with the utmost seriousness and no doubt data protection and prosecution agencies may also do so.

"The only wrongdoing here is by those who have broken the law and obtained private information. It would appear that no stone has gone unturned trying to find a way to undermine our bid including apparently targeting the 14 Olympic Park Legacy Company (OPLC) Board members who had voted unanimously on the bid in our favour.

"The OPLC has confirmed that Ms Knight had absolutely no involvement in the bidding process and we repeat that secret cash was not paid to her.

"We are of the firm view that the integrity of the bidding process has not been compromised. We consider that the bidding process was robust and believe that remains the case."
