Simeon Williamson will team up with Dwain Chambers after being selected for the Great Britain and Northern Ireland squad to compete in next month's World Indoor Championships in Valencia.

Williamson, the European under-23 100 metres champion, will fill the second slot in the 60m event alongside Chambers who was automatically selected after winning the trials earlier this month.

Chambers' selection was against the wishes of UK Athletics, the governing body for athletcis in the UK, due to his drug-tainted past. Chambers has served a two-year ban for using the banned anabolic steroid, THG.

This year the 22-year-old Williamson has lowered his personal best to 6.60seconds in the 60m before finishing second behind Chambers in Sheffield but ahead of European Indoor silver medallist Craig Pickering. Pickering was expected to be Chambers' main challenger but ended up in fifth place.

Pickering and Williamson were then set to go head-to-head at the Norwich Union Grand Prix in Birmingham the following weekend but Pickering pulled out with a virus. The European 100m champion then damaged a hamstring and abandoned his indoor season altogether.

Williamson is one of many British athletes who have supported Chambers' inclusion in the team.

"Dwain has done his time and I have no problem with him running," he said.
