The British Olympics Association banned her for missing three drugs tests, but that was overturned on appeal.

"The BOA ban was not designed to ban for life people who missed three tests in five years, provided they had good reasons," Warner told BBC Sport.

"A one-year ban, which she has served, was proportionate to her offence."

At no time has she been caught with drugs in her system, and she has passed many tests between those missed tests, before and after them UK Athletics chief executive Ed Warner

A one-year ban from all competition was imposed on Ohuruogu in August 2006 after she missed three drugs tests, before she made a dramatic return to action at the World Championships in Osaka, where she won gold in the 400m.

But under BOA rules, the 23-year-old Londoner was also barred from selection for any future Olympic team.

On appeal, this was overturned, and Warner said he did not think was sending out any kind of mixed message.

"The BOA ban was introduced a number of years ago to ban athletes caught overtly cheating," he said.

"We've moved now to a more rigorous system in which, completely by surprise, our testers turn up at places where athletes say they will be or should be.

"At no time has she been caught with drugs in her system, and she has passed many tests between those missed tests, before and after them.
