The last two days has seen a lot of melodrama in the  world athletics meet, at Daegu, South Korea, with the expected loosing and the unexpected winning triumphantly.

The 25-year-old Jamaican, Usain Bolt is famed for entertaining the crowd with his antics before his races, including gesticulating to the camera, but some critics believe he may not have been sufficiently focused before Sunday's race.

Bolt, the 100m and 200m world record holder, gets a chance to make amends for his error as he looks to defend his 200m world title with the heats getting under way on Friday. Bolt eased through his 200m heat at the World Championships in his first appearance at the Daegu track since his disqualification from the 100m final. Bolt, disqualified from the final in Daegu, was criticised for the way he behaved prior to the race amid suggestions it showed a lack of focus.

Idowu cruised into the triple jump final with an opening effort of 17.17m, which turned out to be the fourth best effort of the qualifying round.

Tiffany Porter, who moved from the United States to take up British nationality last year, cruised through the 100m hurdle heats in 12.84, 0.3 seconds behind the favourite, Australia's Sally Pearson.
