Carolina Kluft, the reigning Olympic and World heptathlon champion, has called for drugs cheats such as Dwain Chambers to be banned for life from the sport.

Kluft, speaking in Edinburgh yesterday, as the prelude to this evening's Bank of Scotland Cup meeting at Grangemouth Stadium, emphatically spelled out her view that competitors who test positive for prohibited substances should be drummed out of track and field without any chance of redemption.

"If you have proof that somebody has cheated, and has been caught, why not throw them out?" she said.

"I don't think a lot about Dwain Chambers, because it's his problem, and it's sad, but he cheated and maybe it would be a good punishment if he wasn't allowed to be part of the Olympics again," added the 25 year-old Swede, who is one of the few genuine superstars in her pursuit.

Kluft was responding to the news that the controversial sprinter remains determined to go ahead with a High Court challenge to overturn the British Olympic Association ruling on his Olympic ban, despite a high-profile petition, led by the likes of Dame Kelly Holmes, Sir Steve Redgrave and Chris Hoy, to prevent it.

"Sometimes, it feels as if two years the length of Chambers' original suspension, following a positive test for THG simply isn't enough," she said.

"You find that some people cheat, then they come back and they win again, and it isn't fair on the athletes who are clean, and train hard, and believe in the sport being clean. I don't know, I don't have the solutions, but I do my best to be there for the tests and we all have to keep working together to keep athletics drug free."

Kluft, a redoubtable, larger-than-life personality, who has switched disciplines from her speciality event to the long jump and triple jump in preparing for the trip to Beijing, does not suffer fools or knaves gladly.

Indeed, one suspects that she could fill the role of a one-woman Good Cop, Bad Cop, if required, and her stellar cv, littered as it is with records, medals and major championships, ever since she won the world junior title in 2002, makes her appearance at tonight's proceedings in Falkirk doubly intriguing.

Given her relative youth, there was consternation in her homeland when she announced last March that she lacked the motivation to defend her heptathlon crown in China, but Kluft is neither interested in statistics nor extending her career for the sake of other people.

"I'm taking one year at a time, and I don't make long-term plans, but I don't see myself competing in London at the 2012 Olympics," said Kluft.

"I find my motivation in the joy of training and learning new things, and I trust my heart and my instincts, rather than worrying about what anybody else is doing.

"Now that I am not in the heptathlon, I really hope that Kelly Sotherton her British friend and rival gets among the medals and I am crossing my fingers that she wins the gold. As for myself, when I was young, I never wrote in my diary I want to be the Olympic champion'. I am proud that I did it in Athens, but I have set new challenges for myself, and my dream in Beijing is to jump over seven metres and set a new personal best her current PB is 6.87m.

"Nowadays, everything seems to be about money and medals and how you look, but I cannot make decisions based on how anybody else might react. I just have to do what feels right for me and I hope I can have a good competition in the Olympics and that everybody enjoys my long jumping."

In the midst of a Wimbledon where the women's tournament has been dominated by questions of fashion and femininity rather than playing ability, Kluft's philosophy sets her apart from the fluffy nothings who inhabit other pursuits. Catch her tonight and marvel at poetry in motion.
