Ohuruogu primed for Olympic trials

Defending Olympic 400m champion Christine Ohuruogu looks ahead to this weekend's Olympic trials in Birmingham where she will compete to secure a place on Team GB for London 2012.

The 28-year-old has endured periods of injury since her victory in Beijing four years ago, and was disqualified at last year's World Championships, but says she has been working hard to be in the best possible shape ahead of the 400m trials.

Watch the Olympic trials on BBC Two and this website on Saturday from 16:45 BST, and on Sunday from 17:00 BST.
