The body responsible for a review of Scottish devolution is expected to announce that Holyrood should take control of half of the income tax raised in Scotland, as part of 'radical' devolution proposals. The Calman Commission is expected to call for MSPs to have the power to decide how to raise cash, to be subsidised by a deduction of 10p from standard and upper rates of income tax in Scotland by the Treasury. A cut in the block grant that Scotland gets from the UK government would also form part of the new proposal, the BBC reports. Sir Kenneth Calman, who chairs the commission said: 'Our radical and innovative proposals to introduce a new Scottish rate of income tax will significantly strengthen the accountability of the Scottish Parliament and enable it to serve the people of Scotland better, with a union secure for the future.'
