Sir John Major warned that flirting with leaving the EU was dangerous. Heading off into "splendid isolation would not be in our interests". There would be "acrimonious negotiations" with an "irate ex-partner" if the UK left, it would not save much money, nor better control our borders.
But it would lead, he argued, to a "fractured" UK because of the "high probability" of Scotland voting for independence. And between the lines there was an implicit message for David Cameron to start making similar arguments and not base his campaign to stay in solely on the reforms he hopes to negotiate in Brussels this week.
"This renegotiation is important," Sir John said, "but it shouldn't decide whether or not we remain inside the European Union."
In the Commons the SNP leader at Westminster, Angus Robertson, asked Mr Cameron if he would heed Sir John's advice. The prime minister replied he would get the best deal for Britain.
