Dwain Chambers has raised the stakes in his dispute with UK Athletics (UKA) by easily qualifying for the UK trials for the World Indoor Championships.

The sprinter clocked 6.70 secs in his 60m heat, 6.63 in his semi-final and won the final in 6.60 - a new meeting record at the Birmingham Games.

All three times were comfortably inside the 6.90 secs standard for Sheffield.

However, UKA want to stop Chambers, who has served a two-year drugs ban, from challenging for a place in the GB team.
