But the former Paralympian insisted she will be absolutely impartial when she has to chair a review into UK Athletics' anti-doping policy.

While UKA's hands are legally tied over the selection of one-time banned drugs cheat sprinter Dwain Chambers for next month's World Indoor Championships in Valencia, they intend to tighten the rules to avoid a repeat.

UKA's chief executive Niels de Vos is adamant they should have the right to pick who they want for their country and not be hampered by the current selection criteria.

"I suppose everybody's got their own personal views about drugs in sport, mine is once an athlete has been caught and gone through the legal process, they should receive a long ban," said Grey-Thompson.

"However, I have experience from sitting on different committees, such as those making (decisions over) lottery panel funding, of being totally impartial in my decisions."

Grey-Thompson feels the enforced selection of Chambers for next month's World Indoor Championships makes it necessary for UKA to have rules in place which cannot be legally challenged.

Chambers, who came back into the sport last month and had not been drug tested for over a year, was in UKA's opinion ineligible to represent his country for at least another 12 months. But the International Association of Athletics Federations declared that under its competition and anti-doping regulations he could.

Chambers' victory in last Sunday's 60m trials saw UKA left with little option but to include him given they could face legal action if he was left out.

They could have risked opting to not select him and their decision would certainly not have been over-ruled by the IAAF.

"From looking at the rule book it seems clear that a country's selection policy is a matter for that country – not the IAAF," said an IAAF spokesman.

"But having said that, if UKA refused to select Dwain and he believes that this is unfair, he has the right to protest to the IAAF and, eventually, CAS (Court of Arbitration for Sport) might be the final judge."

The task facing Grey-Thompson and her panel is to ensure in future there are no loopholes, and UKA will formulate plans to exclude drugs cheats from representing their country ever again.

De Vos said: "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."

Grey-Thompson is determined those following in the footsteps of Chambers will be hit hard.

Chambers has not been asked to appear at Saturday's Norwich Union Grand Prix in Birmingham and a leading promoter, Rajne Soderberg, whose Euromeetings Group runs 51 events across Europe, confirmed that Chambers would not be asked to participate in meetings they organise.

Euromeetings, who look after events such as the Golden League, have tough anti-doping measures and Soderberg said their stance was the same for Chambers.
