What will happen to the Olympic Stadium?
With around a year and a half to go until the London Olympics there is still uncertainty over what will happen to the stadium in Stratford after the closing ceremony.
There are two main options and they both involve football clubs.
Either West Ham take it over and keep the running track or Tottenham Hotspur buy the stadium and send in the bulldozers.
A decision on the future of the Olympic Park site is expected this week.
