Alistair Darling: Alex Salmond set to publish 'dishonest' prospectus for independence His latest intervention came as Ruth Davidson, the Scottish Tory leader, predicted young Scots will reject independence next year because nationalism is a "downright old-fashioned" concept in the 21st century. Meanwhile, Willie Rennie, the Scottish Liberal Democrat leader, will today urge all the Unionist party leaders to reassure voters by signing a join statement promising more powers for Holyrood if they reject independence. The pair will join Johann Lamont, their Labour counterpart, and Mr Darling, the campaign leader, at the Better Together launch. With support for independence in the doldrums, the forthcoming White Paper is seen as crucial to reigniting Mr Salmond's hopes for victory. "There is much to give our side confidence, not least the fact that our opponents are so lacking in confidence in their own proposition that their entire strategy now depends on pretending that independence isn't really independence at all," Mr Darling was expected to say. Alex Salmond will argue in the White Paper that Scotland can leave the UK without any consequence. He calls it Indy-lite ... Indy-lite is exactly what it sounds like - a gimmick cooked up by advertising men to get us to buy a product we don't need. The former Chancellor was expected to say that Mr Salmond pretends can Scotland can walk away from the UK while retaining the benefits of its single market, sterling, the armed forces and the BBC. But voters understand that "you cannot leave a club and still expect to enjoy the benefits of membership." Mr Darling was expected to conclude: "Increasingly the independence debate is becoming a battle between those of us offering to continue the success of devolution versus those selling the dishonesty of Indy-lite." Speaking in Edinburgh yesterday to members of a group called Conservative Friends of the Union, Ms Davidson said the referendum offers a choice to "renew a union" which will benefit the next generation. The Scottish Tory leader argued that partnership with in the UK had the instinctive support of a self-confident and ambitious younger generation before contrasting this with the "backward-looking and nostalgic echo of the past" represented by nationalism. A Yes Scotland spokesman said: "With a Yes vote, we will be taking control of our own future and making decisions that match our own priorities and aspirations. And, unlike now under the Westminster system, we will always get the government we vote for.
