A runner the British Olympic Association tried to ban from competing in Beijing has won Britain their first track gold medal.
Christine Ohuruogu powered home over the last 50 metres to win the 400 metres 49.62 seconds.
The 24-year-old won an appeal allowing her to compete in Beijing after she was suspended for missing three out-of-competition drug tests.
Ohuruogu was banned by the International Association of Athletics Federations for one year in 2006 under their strict three strikes policy.
She completed her ban in 2007 but was in danger of missing Beijing after the BOA banned her for life from competing at the Games.
However, she lodged an appeal against the BOA's ruling, which she won, clearing her to compete.
