Dai Greene will race for Great Britain in the 4x400 metres relay final at the Olympic Stadium.

Team captain Greene missed out on a medal in the 400m hurdles, coming home fourth, and will be looking to make up for that disappointment by helping the quartet on to the podium.

The Welshman will run the third leg, with Conrad Williams running the first, Greene's fellow 400m hurdler Jack Green the second and Martyn Rooney the anchor. Nigel Levine has been left out.
