Cameron calls for 'global deal for global problem' at climate summit

UK prime minister to set out his priorities for talks, including legally binding emissions targets, help for poorer countries and a greater role for businesses

David Cameron will set out his personal commitment to tackling climate change at the opening of a crunch UN conference on global warming in Paris on Monday, and will pledge support for poorer countries likely to suffer most from extreme weather.
