article: The prime minister has said Britain will vote on whether to remain in the EU on Thursday 23 June. David Cameron announced the referendum date after a cabinet meeting on Saturday to discuss his deal with the EU he says gives the UK special status. Mrs Foster said the DUP will recommend to voters to leave the EU. "At every stage in this European negotiation process we had hoped to see a fundamental change to our relationship with Europe," she said. "In our view, we see nothing in this deal that changes our outlook. Therefore we will on balance recommend a vote to leave the EU. "As every voter has the opportunity to express a view, we fully expect that DUP members and voters will hold a range of differing personal views as to what is in the best interests of the United Kingdom. "They are fully entitled to do so during what will be a momentous political debate about the direction of travel our nation chooses." The SDLP and Sinn FÃ©in are to campaign to remain within the EU, with the Alliance Party expected to do the same. The Ulster Unionists are still considering their position. Sinn FÃ©in's Martin McGuinness said the benefits of EU membership could "be felt daily across all sections of our society". "In particular, our agriculture and agri-food industry have gone from strength to strength with the help of EU Single Farm Payments," he said. "The EU has also supported key infrastructure projects and boosted our economy through peace and structural funds. "It has also been a key supporter of the progress made in the peace and political processes over the last two decades." SDLP leader Colum Eastwood has said the referendum will be one of the most important votes faced by people in Northern Ireland in decades. "It is therefore vital that a strong and positive campaign is conducted to remain in Europe. "The SDLP's campaign has already begun and today I am calling on the leaders of Sinn FÃ©in, the Alliance party and the Green Party to do their utmost in ensuring that Northern Ireland delivers a strong vote to remain in the EU on 23 June. "I would also urge the Ulster Unionist Party to do what is best for farmers and families and campaign for an In vote." Meanwhile, the Northern Ireland Secretary of State has declared her intention to join the campaign in favour of leaving the EU. David Cameron has suspended collective responsibility over the issue of the UK's future membership of the EU. This means Eurosceptic ministers can campaign in favour of Brexit - against the official government position. Theresa Villiers is one of five cabinet ministers who joined the "Leave" camp. Others include Justice Secretary Michael Gove, Work and Pensions Secretary Iain Duncan Smith, Leader of the House of Commons Chris Grayling, and Culture Secretary John Whittingdale. Employment Minster Priti Patel, who is not a full cabinet member, is also in favour of leaving. Home Secretary Theresa May heads the list of those who have announced they will campaign
summary: DUP leader Arlene Foster has said while her party remains Eurosceptic, members must decide for themselves how to vote in the EU referendum.
