The sprinter easily won the trials held in Sheffield at the weekend but it had been made clear the selectors did not want to pick him because of his drugs past.

Chambers was banned for two years after being found guilty of taking BALCo steroid THG and left the sport to try his luck in American Football.

He has now returned to track and field but as he had not been tested for drugs since November 2006, UKA did not want him to compete at Sunday's trials - or to represent Great Britain at the World Indoors in Valencia.

Chambers was finally allowed to run after his lawyers threatened to take UKA to court - and he won the 60m in convincing fashion in a time of 6.55secs - the fastest in this country this year.

Today he was named in the first wave of 21 athletes that will fly to Spain next month.

But the announcement came with a strongly worded statement:

"Based on his performance at the Norwich Union World Trials, the Selection Committee has selected Dwain Chambers for a place in the 60 metres at the 2008 World Indoors in Valencia.

"In taking this action, however, the selectors wished to issue a statement, which made clear their concerns.

"The Committee was unanimous in its desire not to select Dwain. Taking him to the World Indoors deprives young, upwardly mobile committed athletes of this key development opportunity.

"Our World Class Performance Programme is focused on achievement at Olympic and World level. On this basis, it is extremely frustrating to leave young athletes at home; eligible for Beijing, in possession of the qualifying standard and committed to ongoing participation in a drug-free sport.

"In contrast, we have to take an individual whose sudden return, especially when considered against his previous actions and comments, suggests that he may be using the whole process for his own ends.

"Unfortunately, the committee felt that the selection criteria pertaining to the winner of the trials, coupled with the manner of Dwain's performance, left them no room to take any other decision.

"We wish all the selected athletes well at the event, but will certainly explore ways in which future selections can be made to match the true 'spirit' of our sport."

Also selected in the first wave was Richard Buck, the 21-year-old 400m runner from York who set a new personal best of 46.35s in the final to cement his place in the squad.

Sheffield multi-eventer Jessica Ennis has not yet been selected, although she is expected to be in the second wave announced on February 26.
