Olympic Stadium set to host 2017 World Paralympic Championships Spence said: "We're not going to go to London thinking that we're going to get 80,000 crowds for morning and evening sessions. We know we've still got to reignite that interest because it will be five years down the line. We will have to reinvigorate that interest, but hopefully we'll be starting from a strong position because London was so spectacular for us and everyone got onside and realised the value of Paralympic athletics. The deal for the 2017 event is expected to be finalised before the end of year, making London the first city ever to stage the able-bodied and Paralympic World Athletics Championships in the same year. Meanwhile, Jessica Ennis and David Weir have been voted British Olympic and Paralympic Athletes of the Year for 2012 in a nationwide poll of track fans. Ennis, who won Britain's first track and field gold medal of the London Olympics with a runaway heptathlon victory, took 48 per cent of the vote, defeating double Olympic champion Mo Farah by four per cent. Weir, who won four Paralympic gold medals in wheelchair races ranging from 800 metres to the marathon, also secured 48 per cent of the vote, beating double gold medallist Hannah Cockroft into second place. Both Ennis and Farah have been shortlisted for the World Athlete of the Year awards. The winners will be announced at the International Association of Athletics Federations 100th anniversary gala in Barcelona next month.
