Lord Coe has snubbed Tottenham by offering a passionate support for West Ham's bid to take over the 2012 Olympic Stadium.
London 2012 chairman Coe declared there is a "moral obligation" to ensure that the arena retains a multi-sport legacy when the decision is made on its future on Friday.
West Ham, in a joint bid with Newham Council, want to create a 60,000-capacity facility for football, athletics, concerts and community use.
