Olympics

Olympic experts regularly tell me that London's traffic problems are the biggest challenge to organisers of the 2012 Games.

And it's because of them that London 2012's plans to move badminton to Wembley's indoor Arena in order to save money are likely to face some opposition from the international governing body of the sport.

I've been speaking to the Badminton World Federation where officials are worried about the journey from the athletes' village in east London's Stratford to the arena which is next to the main Wembley Stadium.
