Lib Dems Promise More Tax Cuts
Voters will miss out on future tax cuts worth almost £400 if they back either the SNP or Labour in the General Election, the Chief Secretary to the Treasury has said.
Danny Alexander said workers across the country were £825 better off as a result of the increase in the income tax threshold.
The Conservative-Liberal Democrat government raised the rate at which people have to start paying the tax from £6,475 in 2010 to £10,600, with Mr Alexander hailing the cut in tax for those on "low and middle incomes".
But he said the SNP - which could hold the balance of power at Westminster - had only proposed raising the income-tax threshold in line with inflation in its 2010 manifesto - a policy which he said would have left people £700 a year worse off if it had been implemented.
Mr Alexander pledged that his party would save people a further £400 from their income tax bill in the next parliament - adding that backing another party would mean they would lose out on this.
The Chief Secretary to the Treasury said: "Liberal Democrats have cut tax by £825 for people on low and middle incomes.
"In the next parliament we want to go further and get people another £380 income tax cut.
"Under the SNP or Labour, people will not get that tax cut. We are the only party which has stood up in government for tax cuts for working people.
"We are the only party with a costed plan to give working people more tax cuts in the next parliament.
"The SNP have been firmly opposed to our income tax cuts for the last five years. They have consistently voted against the finance bills that delivered the tax cuts.
"The SNP would have only increased the income tax threshold by inflation from its 2010 level of £6,475.
"If the SNP had got their way, working Scots would have been left counting the cost of a £700 nationalist tax bombshell. That is why you need Lib Dems in government.''
Mr Alexander added: "The SNP have been silent on this in their manifesto. People deserve to know if they will be worse off under their plans.
"A Liberal Democrat vote in this election is a vote for a further tax cut of £400. A vote for Labour or the SNP is a vote to miss out on that tax cut."
