UK Athletics could be paid to quit the London Stadium after the 2017 London Anniversary Games and World Athletics championships.
The cost of moving the relocatable seats rose to £8m last year instead of an original budget of £300,000 and that has caused the stadium owners into considering that as a major alternative.
Claret and Hugh understands that one idea being explored is paying UK Athletics to relocate the Anniversary Games to their UK Athletics home in Birmingham and therefore giving up their 50-year agreement to use the London Stadium.
Buying UK Athletics out of their contract would cost millions but that could still possibly save the stadium owners a fortune should they not need to move the seats each summer.
The purpose-built athletics Alexander Stadium was expanded in 2011 to take a capacity of 12,700 at a cost of £12.5m and already hosts Diamond league events. It is owned by Birmingham City Council.
