West Ham United delivered a final “take it or leave it” offer to the London Legacy Development Corporation yesterday as the saga over the future of the Olympic Stadium enters its end game.

The LLDC insists that it is determined to come to a decision by the end of the year and West Ham’s latest offer, understood to improve substantially on the £10m upfront contribution to the £160m conversion costs previously tabled, is designed to force the issue.

The club are likely to argue that their final offer represents the only chance of guaranteeing a sustainable future for the stadium without ongoing public subsidy. They have indicated they remain committed to moving to Stratford “but not at any price”.
