Shelter wants more social housing to be built

The cheeky posters exposing seven Londoners' behinds aim to entice people to the group's sit-in photographic exhibition on London's South Bank.

The Oxo Gallery is to show more than 5,000 shots of celebrities and members of the public sitting in a red chair in protest at poor housing for children.

Shelter says one million children in Britain are living in poor conditions.

Next generation

Visitors can be photographed and will appear alongside celebrities including TV host Davina McCall, actor Joseph Fiennes and Olympic champion Dame Kelly Holmes in the exhibition.

Shelter wants a commitment from government to end bad housing for the next generation of children and to build more social housing.

Charity director Adam Sampson said the charity had taken the red chair around the UK and succeeded in getting 60,000 people to sign up for their cause.

The idea, he said, came from a suggestion to get people off their backsides.

"We thought we would reverse it and get people to sit on their backsides and do something," he said.
