SIR - It may come as a shock to readers that 64 horses have been killed as a result of racing in Britain this year to date.

Many more have been seriously injured and others have been killed in training.

This awful situation looks set to continue for as long as the racing industry is allowed to remain autonomous and regulate horse welfare itself.

Animal Aid's petition, which urges the government to step in and take action over horse deaths, has been signed by more than 68,000 people. If it reaches 100,000 signatures it will have the chance to trigger a government debate.

Readers who wish to help horses can sign the petition at animalaid.org.uk/horse-petition
