World badminton chiefs will visit London later this month to investigate the proposed switch of their Olympic event from Stratford to Wembley.
The Badminton World Federation are concerned about journey times from the Olympic Village and have requested a site visit. A final decision will not be taken before March.

Organisers initially tried to persuade boxing to move, but have now turned to badminton and rhythmic gymnastics.
Switching the events would save £20million in building costs.
