UK 29 April 2015 Conservatives offer a five-year freeze in tax cuts: will it have any effect? The Conservatives' unworkable bribe sounds too good to be true - because it is. Splash the cash.

Sign-up The Conservatives will today seek to reclaim the political agenda with a promise to outlaw any rises in income tax, VAT or national insurance for the next five years. That’s on top of an extra £8bn a year, a cut and a cap in train fares. . . and they’ll do all this while moving the budget into surplus by 2020. Presumably, if the polls haven’t moved by next Tuesday, they’ll throw in a free unicorn for every adult in a swing seat. I don’t know where to start with this, honestly. The pledge is obviously crazy – what happens if you outlaw tax rises, and say, a bank collapses? Or the Eurozone needs a cross-country stimulus to prevent sucking the whole continent into recession? Or Britain’s defence needs are suddenly radically different? Will it work? As one Labour MP observed recently, “people like free stuff”. People who’ve had a fairly awful half-decade or more like free stuff even more. More importantly, it’s the first Tory message of the short campaign that can be broken down into a pleasing goodie for a two-minute news bulletin. Repeated over and over again for the campaign’s final seven days, coupled with further warnings about the SNP, it might be enough for the Conservatives to blunt Labour’s advantage in England and Wales and remain in office. But will it? Visiting the Welsh marginals last week, the number one reason people gave for backing the Conservatives was that they needed time to finish the job, something I'm told is a repeated refrain on the doorsteps. If there is money available for a freeze in tax rates and further spending, it doesn't sound as if the mission is half-done and Labour are too big a risk. It sounds as if the good times are here again, and maybe it's time to give Miliband a crack of the whip. David Cameron and George Osborne have spent the last five years saying that there is no money left, that we have to tighten our belts, that the recovery is either just around the corner, or too fragile to risk Labour’s extra borrowing and more debt. That appeals to what one Conservative describes as the country’s “Blitz spirit” – and means that, for all the pain of the last few years, people are still inclined to give Cameron the benefit of the doubt. And it's not so long ago since the coalition's final budget, when Osborne had the opportunity to hand out tax cuts - but didn't. It's one thing for the Tories to have a message that is attacked by Labour and the Liberal Democrats, but quite another to have a policy that runs contrary to everything they've done and said for the last five years. Far from turning the election in their favour, they may have just tilted the battle in Miliband's direction. › You can't betray the revolution: why Egyptian activist Alaa al-Aswany likes being a dentist Stephen Bush is political editor of the New Statesman.
