West Ham remain confident their move to the Olympic Stadium will go ahead despite the granting of a judicial review for Spurs and Leyton Orient to challenge the decision.

A statement on the Hammers website said: "We acknowledge that the final hurdle of a Judicial Review against London of Borough of Newham and the OPLC in relation to West Ham United being the preferred bidder for the Olympic Stadium has been granted on a very narrow basis.

"A full hearing will take place on 18 October and we remain confident that Newham and the OPLC will be successful in defending limited points regarding the £40m loan that would be made to the Legacy Stadium Partnership.

"Separately, and only for clarification as we have been inundated with inquiries with regard to a Scotland Yard statement today, we confirm the Metropolitan Police's Economic and Specialist Crimes Unit is dealing with the serious matter of a private investigator acting unlawfully, reportedly under instruction by Tottenham Hotspur.

"This is in relation to reported breaches of the Data Protection Act and Computer Misuse Act as a result of the unlawful acquisition of bank and telephone records belonging to senior executives at the club and the OPLC.

"We are advised that if found guilty of these crimes, those responsible can expect to receive custodial sentences. We have full faith in the police investigation into this matter and shall continue to provide the fullest of assistance to them.

"In response to media inquiries, we can confirm that West Ham today received a document from Tottenham asking us to give up our claims against them in relation to the above, in return for Tottenham withdrawing their judicial review proceedings. West Ham naturally refused.

"We look forward to the 18 October and a successful conclusion whereby we can deliver the multi-sport legacy that Lord Coe envisaged for east London and the rest of the nation."
