Britain name Williamson as second sprinter for Valencia

Simeon Williamson will line up alongside training partner Dwain Chambers in the 60m at the World Indoor Championships in Valencia next month after being named in the final squad. Williamson's inclusion follows impressive performances at the World Indoor Trials, where he finished runner-up to Chambers, and at the recent grand prix event in Birmingham, where he lowered his personal best to 6.57 seconds.

Great Britain's selections for the event have been the focus of heated debate after Chambers, who served a two-year ban for a doping offence, forced UK Athletics' hand by winning the trials. Williamson, who backs Chambers' inclusion, takes the final spot following the withdrawal of Craig Pickering, who has been forced to draw a line under his indoor season after sustaining a hamstring injury. Rikki Fifton will travel as a reserve for the event.

Meanwhile Mo Farah, the European 5000m silver medallist, has been selected for the 3000m, in which he will compete alongside Nick McCormick. Michael East will continue his return from serious knee problems after being selected for the 1500m. It will be his first appearance in international competition since 2006.
