Gold and silver for Britain

Great Britain claimed gold and silver in the women's 400 metres at the World Championships in Osaka with Christine Ohuruogu taking first place just weeks after completing a 12-month ban for missing three drugs tests.

Ohuruogu, 23, finished in 49.61 seconds, just ahead of fellow Briton Nicola Sanders, 25, as both runners overhauled Jamaica's Novlene Williams on the home straight.

Ohuruogu said: "It'll sink in later for me, I've just won a race."

Ohuruogu insisted her success was just reward for the hard work put in during her ban.

"It was very hard," she admitted on BBC2. "But I am very proud of myself because I had operations on both legs, I trained, got up every day and did my work.

"I trained hard, always with the World Championships in mind. It (winning) was all a dream, you hope you would, but to have gone and done it..."

Ohuruogu hopes her rivalry with Sanders will help to set the standard for a new era of British athletics.

"It was very close," she said of the race. "It is very good in terms of competition, it's what Britain needs right now, people competing at the top level. I hope that people take a leaf out of that."

Sanders also ran a personal best, 49.65secs, to make it a British one-two, and admitted afterwards she had not been sure of her position as she crossed the line.

"I had to just convince myself and just concentrate on my own race," she told BBC2."I didn't have a clue what had happened, I just lunged for the line. It's awesome, you can't ask for more. It's fantastic."
