A London Underground station has been taken over by cats - with all advertisements replaced with pictures of the animals.

Almost 700 people helped the Citizens Advertising Takeover Service (Cats) raise £23,000 to buy the advertising space at Clapham Common station.

The cats will appear on advertising boards for two weeks from 12 September.

The aim is to provide a "relaxing, fun and light-hearted" space free from commercial adverts, Cats said.
