Katie Walsh: Irish Grand National winner on equality in racing

This year's Irish Grand National winner Katie Walsh hears some strong and divergent opinions while exploring the issue of equality for women in horse racing.

Michael Tebbutt, a coach at the British Racing School, tells Walsh that opportunities for women to become top jockeys are limited because "it boils down to strength".

However, chair of Women In Racing Sally Rowley-Williams argues that relative strength of male and female jockeys is "irrelevant".
