Steve Cram column

By Steve Cram BBC Sport commentator

The time has come to draw a line under the whole Dwain Chambers saga now he has won silver at the World Indoor Championships.

I'm pleased the whole thing has come to and end; he can get on with what he wants to do and the sport can move on.

Chambers was the centre of media attention in Spain

Is this the end of Chambers? I don't know. He's said he wants to go away and have time to think so we'll have to wait and see.

Despite his performance, it looks likely that it could be the end of his athletics career.

He won't be able to compete in European meets this summer, because the organisers have agreed not to invite athletes convicted of drugs offences, and none of the agents will be able to represent him.

Chambers also has a lifetime ban from the Olympics and I don't know if he will contest it.

I support the British Olympic Association's stance because you have to make it harder for athletes who have been guilty of serious drug offences to come back.

There is a growing acceptance in athletics and in other associations, like the World Anti-Doping Agency, that a two-year ban is no longer enough.

It's not just Dwain Chambers that is here in Valencia competing, there are other athletes who have served bans in the past and are now back at the highest level. It's just too easy to come back and do well.

No-one is arguing about whether Chambers is or isn't a good athlete.

606: DEBATE Jeanette is a good-luck story. Hopefully she'll be strong enough to convert herself into a world-class 100m athlete PTRP

But the one thing I will say is that he ran 6.55 seconds back in 2000 when he'd just come off the juniors and had his whole career ahead of him.

He then chose a particular route and, yes, a lot of things have happened that have not been nice for him, but he chose that.

It's taken him eight years to improve by one hundredth of a second over 60m. Now, it's time to move on.

I felt sorry for the gold medallist Olusoji Fasuba as all the media gathered round Chambers at the end of the race.

That just shows where we're at; people want to know more about the controversial figure than they do about the winner.

On a more positive note, it was a good day for Great Britain.

Kwakye and Sotherton also won silver medals in Valencia

Jeanette Kwakye was absolutely superb as no-one would have predicted she would win a silver medal and set a new British record in the women's 60m.

She just got better and better through the rounds and came to within inches of winning the gold.

I have spoken to her coach Mike Afilaka and he's over the moon because he's been telling us how good she is for ages!

Kwakye has had an injury-ridden couple of seasons and the important thing is that she builds on this now over 100m in the summer.

British women's sprinting needs somebody to take it back to world class and Kwakye has a chance to do that.

As for Kelly Sotherton, I saw her on the way out and she just said to me "high jump".

Winner Tia Hellebaut is a great athlete but Kelly knows the title was up for grabs and I think she was disappointed with the silver.
