There are fears that a riding centre which supports 340 people a week will miss out when ULEZ is rolled out this summer.

The Diamond Centre in Carshalton and is a 30-minute walk from the closest train station. 

They say many of the centre's disabled riders simply won't be able to get to their sessions.

At the end of August, the £12.50 a day charge for the most polluting vehicle will be extended to cover the whole of London.
