Usain Bolt beat Justin Gatlin by one hundredth of a second to retain the 100m title at the World Athletics Championships in Beijing.

Bolt had stumbled out of the blocks in winning his semi-final but found a season's best run of 9.79 seconds to win the title for the third time.

America's Trayvon Bromwell and Canada's Andre De Grasse were both awarded a bronze medal after clocking identical times of 9.911secs.

In this clip, our athletics correspondent Mike Costello describes the race, with former British sprinter Darren Campbell giving his reaction to the result.
