The stunt mirrored a similar action when a men’s magazine projected naked images of TV presenter Gail Porter on Parliament in the late 90s as a promotional stunt.

This time the projections, last night (30 September), were less crude and showed Christian Aid supporters including actress Greta Scacchi.

Ms Scacchi, and the protesters, called on the international community to agree a fair climate deal at Copenhagen.

There were also messages urging UK prime minister Gordon Brown and US president Barack Obama to lead the fight for climate justice at the summit.

Christian Aid’s head of campaigns, Paul Brannen, said after the protest: “We chose Parliament as we want politicians to understand the very real nature of the crisis that is developing and act accordingly.

“It is rich industrialised countries like the UK that are historically responsible for causing climate change.

“They must now demonstrate a new kind of leadership in dealing with the consequences.

“It’s time for a new revolution, a climate revolution. It’s vital that a fair and just climate deal is agreed in Copenhagen to come into force when the first phase of the Kyoto Protocol ends in 2012.”
