THE five political parties represented in the Scottish Parliament yesterday submitted their proposals for powering up devolution to the Smith Commission.

Labour, SNP, Tories, Lib Dems and Greens each submitted separate plans in response to the commission set up after last month’s independence referendum.

SNP deputy leader Nicola Sturgeon pledged that the party would play “a full and constructive” role in the commission.

“This will include working to ensure that the outcome meets the high expectations of the people of Scotland as expressed in the referendum, given the various promises of ‘devo max’, ‘near federalism’ and ‘home rule’ which were made,” she said.

The SNP proposes full responsibility for all taxes and domestic spending, including welfare, to be transferred to Holyrood — with payments made to Westminster for reserved services.

Scottish Labour submitted the recommendations of its own Devolution Comission which reported in March, under which the Scottish Parliament would have power to raise 40 per cent of its own budget, implement progressive taxation and control housing benefit and attendance allowance.

The Scottish Conservatives said its Strathclyde Commission proposal published in June for full devolution of income tax and the assignation of a share of VAT would be a “starting point” for further discussion and “a floor rather than a ceiling.”

Meanwhile the Lib Dems propose “home rule” for Scotland as part of a move to a federal system across the UK — with control over income tax, inheritance tax and capital gains tax plus the assignation of proceeds of corporation tax raised in Scotland.

The Scottish Greens want economic powers including borrowing and taxation as well as the majority of the welfare system transferred to Holyrood, along with energy powers related to industrial emissions standards, community renewables and public energy companies.
