New tax powers should be used to make the rich pay more and stop cuts to schools and public services, the Scottish Labour leader Kezia Dugdale has said. Speaking at a campaign stop in Rutherglen on Saturday, Dugdale called on the next Scottish Parliament to stop "acting as a conveyor belt for Tory austerity". She outlined Scottish Labour's top three priorities for the next parliament as: Citing analysis by think tank IPPR Scotland that Labour's tax proposals would raise £900m more than the SNP's by 2020/21, the Labour leader said the extra money could pay for her proposals. Dugdale said: "The central issue in this election is about how each party will use the new powers over tax to stop cuts to schools, the NHS and other public services. "Labour will use the powers to ask the top 1% to pay the most and stop the Scottish Parliament acting as a conveyor belt for Tory austerity. "That's the positive message activists and trade unionists will be making on high streets and doorsteps all across Scotland this weekend." She added: "The SNP have forced hundreds of millions of pounds of cuts on to schools and public services. We don't have to accept those cuts, we can take a different path from Tory austerity." An SNP spokesperson said: "So far in this campaign, Labour's big idea is to shift the burden of Tory austerity onto those who can least afford it with their tax hike on low earners. "People will be astonished that while Scottish Labour plan to hike taxes for the lowest paid workers, the party will not oppose spending £167bn on new nuclear weapons at Westminster - money which should be spent on public services, rather than on weapons of mass destruction. "In contrast, the SNP are the only party in Scotland with the strength, unity and vision to keep our economy moving forward with ambitious plans to boost our productivity, create more and better jobs and support our public services." Campaigning in Bridge of Allan, Scottish Liberal Democrat leader Willie Rennie said he would put education "at the heart of the next parliament". Rennie said: "Our education system used to be a world leader but it's slipped down the international rankings in recent years." On his party's plans to raise 1p on the basic rate of income tax to fund education, Rennie said: "Our penny for education would make such a difference. It means more kids who are struggling getting the help they need to get on in life." The Scottish Lib Dem manifesto, unveiled in Edinburgh yesterday, vowed to use its 'penny for education' to reverse college cuts and double early education and childcare for three and four year olds. Co-convener of the Scottish Greens and social justice spokesperson Maggie Chapman claimed only her party would use new tax powers to combat inequality. Chapman said the Greens' plans ensured "everyone earning less than £26,500 would get to keep more of what they earn. Labour's across the board rise would hit those on lower than average incomes." She added: "Under our proposals to replace council tax the majority of households would pay less, so altogether it is clear that the Scottish Greens are making the boldest, most progressive offer in this election." The Scottish Conservatives have also been approached for comment. Download: The STV News app is Scotland's favourite and is available for iPhone from the App store and for Android from Google Play.
