League One - Orient demand stadium review
Leyton Orient chairman Barry Hearn has written to Prime Minister David Cameron and London Mayor Boris Johnson asking them to look again at the decision to award West Ham the Olympic Stadium and is taking legal advice over the possibility of a judicial review.
West Ham were named the preferred bidders by the Olympic Park Legacy Committee - a decision which must still be ratified - but as the club closest to the site, Orient believe their very existence would be threatened by the arrival of the Hammers.
Hearn is in talks with his legal team about a judicial review, which could significantly delay the process of confirming West Ham's tenancy, and has outlined his concerns to Cameron and Johnson as well as Jeremy Hunt, secretary of state for Culture, Media and Sport, and Hugh Robertson, Minister for Sport and the Olympics.
Hearn said: "It's a question of due process and whether the Olympic Park Legacy Committee, the Department for Culture, Media and Sport and even the Prime Minister have given consideration to Leyton Orient in these discussions."
