The British 4x100m relay team have lost the silver medals they won at the World 2003 World Championships because of Dwain Chambers' failed drugs test.

Chambers tested positive for the banned steroid THG last year and was handed a two-year ban from athletics.
The International Association of Athletics Associations (IAAF) has now annulled his results from Paris.
The other runners who lose out are Marlon Devonish, Christian Malcolm and Darren Campbell.
Chambers ran the anchor leg in the relay in which the
United States won gold.
Brazil replaces Britain as the silver medallist, with the Netherlands taking bronze.
"The decision has been made, I can't do anything about it,"
said Campbell in a statement issued by his agents.
"I'll have to
go with it and give my medal back. It will just lift and inspire
the team more to achieve at the Olympics in Athens."
The IAAF said all of Chambers' performances would be
annulled from the date of his positive test - 1 August, 2003.
Also voided were Chambers' fourth-place finish in the 100m final at the World Championships, and his fourth place in the 100m at the World Athletics Final on 13 September.
The IAAF moved to erase Chambers' performances from the record books following the expiry of the deadline for any appeal to the Court of Arbitration for Sport (CAS).
Chambers had already indicated he would not appeal against his two-year suspension.
The European 100m champion has always denied knowingly taking THG.
A spokeswoman for UK Athletics said: "As Dwain Chambers has chosen not to appeal, his case is now concluded.
"UK Athletics and the athletes in the 4x100m squad were always aware that in this situation the performance of the whole squad at the World Championships would be annulled and we accept that decision."
