 The decision in favour of West Ham 's bid was unanimous , although controversial as local rivals Tottenham Hotspur had also been bidding for the venue . However , hopes of moving to the stadium were since placed under doubt following a legal challenge by Tottenham Hotspur and Leyton Orient . With Leyton Orient fearful that having West Ham playing less than a mile away from their Brisbane Road ground could steal support from the club and put them out of business . However both clubs appeal for a judicial review were rejected on 23 June 2011 . On 3 March 2011 West Ham United 's proposed move to the Olympic Stadium was formally approved by the British government and Mayor of London Boris Johnson .
