Those details have been made public ahead of Friday's vote for the 2017 world athletics championships where London is bidding against Doha. Any football club that becomes a tenant - and London mayor Boris Johnson has already said that is 'almost certainly' to be West Ham - will however have to agree that athletics takes priority for major events.
UK Athletics chairman Ed Warner said: 'We have been able to communicate to all members of the IAAF council that athletics will be guaranteed in the stadium for 99 years. Ready to move in: West Ham want to head to the 2012 stadium 'Athletics will have primacy in the summer months and the stadium will have track and field at its heart.
'We also have a right to host a major competition every few years provided we give the landlord two years' notice, and any football club will have to arrange to play away from home during those competitions.'
Warner also announced that teenage sprint star Jodie Williams will play a key role in London's presentation to the IAAF on Friday. Williams, 18, the world and European junior champion at 100m, will address the IAAF council in Monaco on London's behalf.
