West Ham United can confirm the club are taking legal action in relation to allegations made in today's Sunday Times.

We are certain of the robustness of our successful bid for the Olympic Stadium.

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 suggestion of 'secret cash' in the Sunday Times article is absolutely and categorically denied. As such, legal action is being taken against the Sunday Times, as well as Tottenham Hotspur.

Dionne Knight's work for the Legacy Stadium Partnership (LSP) owned 50% by London Borough of Newham and 50% by West Ham United was in relation to the procurement of a construction partner after the Olympic Games.

A number of companies applied for the procurement contract. It was awarded to Ms Knight as she was able to provide expertise at a significantly competitive price. The work that she subsequently undertook for the LSP was of a very high standard.

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.

Her work was very transparent and the bidding process was never compromised. The work was never hidden, for example she personally attended meetings. There is considerable documentation to confirm the existence and quality of her work. Two firms of solicitors are able to confirm those facts. The price we paid for the work was extremely competitive.

The LSP, including Karren Brady who is named in the offending article, has not paid any member of the OPLC for any information in relation to the bid process, and has not received any unauthorised information from the OPLC or any other source in relation to its bid.

The OPLC has further confirmed that she and other employees of the OPLC did not have access to confidential information as it was held at the OPLC's external solicitors' offices.

The LSP believed Ms Knight had authority to do the work as that was what it was informed. The fact that the work was undertaken is wholly irrelevant to the Olympic Stadium bid process and only raises issues of employment law.

To reiterate, the allegations are the subject of legal action. If there is any further publication of the allegations, further action will be taken.

We are so confident in the probity of our actions that we will take the strongest action possible against any suggestion of wrongdoing on the part of West Ham United or its officers, as well as involve the police and the data protection registrar in regard to the accessing of private information by illegal means.
