Caution or pusillanimity?

All that effort to acquire powers over tax.  And, having acquired such powers, the SNP disdains their use.  The BBC website notes:

So the offer on tax is to thwart the chancellor's proposed tax cut for higher earners which is achieved by raising the threshold for the 40p rate from £42,000 to £45,000.

Instead of that, the threshold in Scotland will only rise by CPI inflation - as I forecast a wee while back. (In fact, the entire package will have come as no surprise to regular readers of this site.)

Ms Sturgeon and her deputy John Swinney said their plan meant nobody in Scotland would pay more than they presently pay. Some would pay less. But some would pay more than folk in the rest of the UK.

That, they said, would generate productive revenue for public services in Scotland - which they multi-counted to reach a figure of £1bn over the lifetime of the next parliament.

Looking ahead, the first minister also envisaged an enhanced personal allowance of £12,750 by 2021-22 - with the prospect of a zero rate band to achieve that, if necessary.

Throw in the modest changes to council tax, and it is a policy of steady as she goes.
