Christine Ohuruogu produced another thrilling late surge in the 400m to become the first British female to win two World Championship titles.

The 29-year-old also broke Kathy Cook's long-standing British record by two hundredths of a second as she beat defending champion Amantle Montsho in a photo finish.
Both Ohuruogu and Montsho clocked 49.41 seconds, but it was the Briton who was deemed the winner by four thousandths of a second.

Ohuruogu's medal collection

• Olympics: 400m gold (2008) and 400m silver (2012)
• World Championships: 400m gold (2007 and 2013) and 4x400m relay bronze (2005 and 2007)
• Commonwealth Games: 400m gold (2006)
• World Indoor Championships: 4x400m relay gold (2012)
• European Indoor Championships: 4x400m relay gold (2013)

Ohuruogu, the 2007 world champion, gasped in astonishment as she learned of her victory.

Montsho, 30, had victory within her grasp and even as the two athletes stood on the finishing line, anxiously awaiting the final result, Ohuruogu gave the impression that her perfectly-timed dip had not been enough.
But after closer inspection, it was revealed that the Londoner had crossed the line in 49.404, while Montsho, who failed to dip, finished in 49.408.
Ohuruogu, who had been fourth coming round the final bend after a steady start, shook her rival's hand before draping herself in a giant union flag to celebrate her victory.
The Briton told BBC Sport: "I can't believe I've done that, it feels like a dream. It is what I have been working towards all season.
"It was so tight on the line and I was so desperate to win it. I just wanted my name to come up.
