World Championships 2015: Great Britain men win 4x400m bronze

Great Britain's quartet of Rabah Yousif, Delanno Williams, Jarryd Dunn and Martyn Rooney win a dramatic bronze in the men's 4x400m relay at the World Athletics Championships.

The team looked set for a fourth place finish after Jamaica's Javon Francis took the lead on the final lap, but Rooney remained calm and pipped him at the line.

The USA took gold while Trinidad and Tobago won silver.
