SCOTTISH leaders of all political parties have been challenged by a coalition of nature charities over their lack of urgency in tackling climate change.

Twenty-six groups have joined to write an open letter aimed at the leaders of the five parties represented at Holyrood — the SNP, Conservatives, Labour, Greens and Liberal Democrats.

The organisations, including RSPB Scotland, Friends of the Earth Scotland, WWF Scotland and the National Trust for Scotland, insisted they were “deeply concerned” about the situation and the lack of action from political leaders.
