RSPB and WWF urge backers to vote to stay in EU to protect UK wildlife

Charities say Brexit would mean 'years of uncertainty', as David Cameron pledges to protect birds and habitats directives

Two of the biggest conservation charities in Britain, the RSPB and WWF, have joined forces with David Cameron to urge their 1.7 million supporters to protect the UK's environment by voting to stay in the EU.

In a joint article published on Thursday, the two charities say that "years of uncertainty" would follow a vote to leave. "The safer option for our wildlife and environment is for the UK to remain within the EU," they say.
