“We put forward in our manifesto the clearest possible pledge of an in-out referendum by the end of 2017. That has now been backed in a UK General Election and I believe I have a mandate for that,” he told the newspaper.
“They didn’t give Orkney and Shetland an opt-out, or the Borders an opt out [during the Scottish independence referendum] so this is a UK pledge, it will be delivered for the UK.”
Mr Cameron’s assertion is a rejection of calls from Scotland’s first minister Nicola Sturgeon, says she wants a “lock” to be put on Britain’s EU exit.
Under such an arrangement, England, Scotland, Wales, and Northern Ireland would all have to vote to leave the European Union for the UK to quit the block.
Ms Sturgeon has said a situation where the UK left the European Union against Scotland’s wishes could lead to another independence referendum.
“But I actually want to have an arrangement to stop that happening,” she added, a reference to her triple-lock deal.
Recent surveys conducted by all pollsters have found a strong plurality of voters in favour of staying in the European Union.
The latest survey by YouGov found that 45% would vote to stay and 36% would vote to leave. The polls are volatile, however. In January and February two surveys by Opinium and TNS-BMRB respectively found people voting to leave.
