Stadium track must stay - Gunnell

1992 Olympic 400m hurdles gold medallist Sally Gunnell says the athletics track at the Olympic stadium in Stratford "needs to stay" in order to retain its sporting legacy.

London is bidding to host the 2017 World Championships, and Gunnell welcomes the backing of the bid by the Prime Minister, saying she "believes we can get it".

London 2012 chairman Lord Coe has previously rejected claims the Olympic Stadium is set to become a "white elephant".
