Comedian to swim Thames

LITTLE BRITAIN star David Walliams is braving raw sewage and deadly diseases to raise money for charity by swimming the length of the Thames.

The comedian will be setting off from Ledbury on the Herefordshire-Gloucestershire border and will swim 225km over eight days to reach Big Ben in London.

Walliams’ epic swim will also see him brave bitingly cold river water, which can cause cramp and breathing spasms.
