Suffragette Emily Davison remembered on Derby Day

A crowd of more than 100,000 people are gathering at Epsom Downs on Saturday to see some of the finest racehorses in the world in this year's Derby.

The horses will thunder past a plaque commemorating the moment 100 years ago when suffragette Emily Wilding Davison ran onto the course and was knocked to the ground by King George V's horse Anmer.

She died from her injuries four days later in hospital, and the suffragettes quickly established her as a martyr for votes for women.

Mark Denten looks back on the events of that day, and the legacy Emily Wilding Davison left behind.
