The head of Greenpeace has said that it is justifiable to break the law in order to alert people to the threat of climate change.

Kumi Naidoo said the organisation had no intention of scaling back its tactics as he compared protesters' actions to Mahatma Ghandi, Nelson Mandela and Martin Luther King saying they too broke the law.
"In some ways we will probably intensify it because all the science is telling us that time is running out for this planet," he said.
However he emphasised that the group was "deeply committed to peace" and would not resort to violence.
Last week 54 Greenpeace protectors were charged with trespass after spending the night on the roof of the Houses of Parliament in October last year.
