Alex Salmond accuses David Cameron of 'double dealing' over EU and Scottish referendums However, support for separation has fallen to 35 per cent and the First Minister is refusing even to enter negotiations with the Government while he tries to whip up support for a second question. Mr Cameron yesterday told the Commons that the British public should provide "fresh consent" for EU membership, possibly using a referendum once stability in the eurozone has returned. Responding to the statement, Mr Salmond said: "It is extraordinary that the Prime Minister should be suggesting a referendum on the European Union while apparently oblivious to the contradictions it reveals in his attitude towards Scotland's referendum. He is suggesting an EU poll without any definition of what the question would be, at a time hitherto to be specified for which he has no electoral mandate whatsoever, while at the same time threatening to obstruct a Scottish poll for which there is a clear mandate and timetable. He added: "The Prime Minister should realise that in Scotland his new-found enthusiasm for a poll on the EU will be regarded as hypocrisy. He will stand accused of double dealing and doublethink. But Ruth Davidson, the Scottish Tory leader, said: "This is just more bluster and assertion from Alex Salmond, who is clearly trying to divert attention away from his attempts to get a second question on the ballot paper. It is high time he stopped his carping from the sidelines and accepted the offer from myself and the other opposition leaders to get back round the negotiating table. The First Minister and Mr Cameron are at loggerheads over the number of questions that should appear on the ballot paper. Despite supposedly campaigning for separation, Mr Salmond has risked infuriating his party by arguing that devo max would be a "very attractive" alternative. The First Minister is threatening to stage the vote himself, but this would be likely to be struck down as illegal by the courts. Mr Cameron is known to be considering seizing control of the referendum if Mr Salmond continues to prevaricate. A series of election experts have already stated that the First Minister's preferred referendum question is biased by asking voters if they "agree" Scotland should be independent, a phrasing that invites a positive response. Patricia Ferguson, Scottish Labour's constitutional spokesman, said: "This is classic opportunism from Alex Salmond. David Cameron and Alex Salmond have more in common than they would care to admit when it comes to referendums - both seem more concerned with party politics than what is best for the country.
