A banner with the slogan: "Change the politics, save the climate" was unfurled
More than 50 people have been charged after a climate change protest on the roof of the Houses of Parliament.
Fifty-four are accused of trespassing on land designated a protected site, while the other person is charged with helping to plan a trespass.
Several dozen Greenpeace activists spent the night on top of the Palace of Westminster in October 2009.
Yellow banners were unfurled with the slogan: "Change the politics, save the climate".
The demonstration coincided with the return to Westminster of MPs who had been on their summer break.
Those who have been charged range in age from 21 to 70 and come from towns and cities across the UK.
They are all due to appear before City of Westminster Magistrates Court on 23 or 24 March.
