Northern Ireland's Democratic Unionist Party will not agree a deal to support Prime Minister Theresa May's Conservatives in government before the start of next week at the earliest, a DUP source said on Friday. May's Conservatives have been in talks with the DUP after the prime minister's party failed to win a majority in a national election last week. 'If there is the expected positive outcome, it will be at least the start of next week before anything is signed off,' a DUP source said.
