Dame Tanni Grey-Thompson has been appointed by UK Athletics to lead a review of their anti-doping policy. The selection of the retired Paralympian follows the governing body's reluctant decision to pick 29-year-old sprinter Dwain Chambers for next month's World Indoor Championships in Valencia.

"My mandate is clear and I believe the time is right for UKA to play a leading role in driving change through athletics to ensure that drug offenders cannot walk back into our sport unchallenged and untested," Grey-Thompson said. "We will lobby relentlessly to increase the penalties for drugs cheats."

The anti-doping review will consider the possibility of extended or lifetime bans from representing GB, the right to control entry into UKA events and how future selection policies are framed.

Niels de Vos, UKA's chief executive, said: "I am delighted that Tanni has agreed to chair our review panel. She is one of the greatest athletes this country has ever seen and is a passionate advocate of drug-free sport. She has the respect of the global sporting community and will ensure the review delivers well thought-out and robust solutions.

"Athletics must act now, and must act decisively, to strengthen its own ability to select the athletes it wants to select. Representing Great Britain must remain a privilege and not a right and the review will ensure the sport never finds itself in such a position again."

It is intended the review will in future give UK Athletics the right to choose whichever athletes they want. They were unaminous in their desire not to pick Chambers, preferring to groom younger sprinters in preparation for future major events. But, after denying the likelihood of legal action by the athlete had swayed their decision, they eventually complied with their selection policy.
