Yohan Blake and Usain Bolt were again the star attractions at a cold and drizzly Diamond League meeting in Zurich.

Usain Bolt brought the track action at London 2012 to a fittingly brilliant close tonight, anchoring the Jamaican 4x100m relay team to gold in a new world record.

Ireland's Annelise Murphy is in with a medal shout in the Laser Radial class with only one point separating the top four.

The United States have clinched four golds on the final day of the World Indoor Athletics Championships, a fifth was removed when the men’s 4x400m relay team was stripped of gold.
