A ROW over changes to income tax in Scotland erupted today after Labour warned that public services will suffer under the SNP plan — and chief executives will pay less tax.

Speaking ahead of a vote in the Scottish Parliament this Tuesday on income tax rates, SNP Finance Secretary Derek Mackay argued his party’s strategy was moving Scotland towards a “more progressive tax system.”

He said: “The Scottish Budget proposes an additional £2 billion of investment. It provides an increase of almost £730 million for health and care services, more than £180m to raise attainment in our schools and gives a vital boost to our economy through a £5bn infrastructure programme.
