I suspect taking on the Olympic Stadium would bankrupt UK Athletics - they're incompetent at the best of times; see the way they allowed their sponsorship with Aviva to end without any replacement, claiming they were looking for "Champions League" style multi sponsorship. So far they've ended up with McCain...
Is it not possible to have a new home? Especially one at, you know, the Olympics stadium?
Spurs ideas for the Olympic stadium were great. Especially offering to turn Crystal Palace back into a world class athletics venue. You know, the actual home of athletics in this country.
Not that their idea was bad (I still would reject spurs moving close to me), but that crystal palace being the home argument is a bit flawed.
