According to UK newspaper the Guardian, Johnson met the Olympics minister Tessa Jowell to sort out a compromise ahead of the latest meeting of the full Olympic board on Thursday.
At the last Olympic board meeting Jowell proposed building a new venue for badminton and rhythmic gymnastics in Barking, claiming it would be cheaper than building it in Greenwich, thanks to the involvement of private investors, and would leave a lasting legacy for Barking. However private funding promised for the Barking development was not guaranteed and upgrading Wembley for the Games proved cheaper than first thought.
The agreement should save organisers more than £20 million. In return, Johnson has agreed to drop his campaign to move the shooting events from the Royal Artillery Barracks in Woolwich to a cheaper alternative in Barking.
Badminton is holding its 2011 World Championships at Wembley Arena and organisers hope to persuade the sport it will provide a better showcase than a temporary arena.
