The Green Party's mayoral candidate Darren Johnson joined Richmond and Wandsworth GLA candidates on their bikes around the park as part of a tour organised by the Merton Cycling Campaign.

"We are calling on the Royal Parks Agency to take measures needed to put an end to rat-running traffic in Richmond Park," said Mr Johnson.

"As life in the capital gets faster, the benefits of tranquil green spaces, such as Richmond Park, to the health of Londoners cannot be under-estimated."
