Scotland should brace itself for bigger public spending cuts than originally thought, according to the country's chief economic adviser.

Dr Andrew Goudie carried out a revised study of Scotland's finances in the wake of the coalition UK government's emergency budget.

He estimated a public spending squeeze of £42bn over the next 16 years.

This is significantly more than the £25bn to £35bn over 12 to 16 years which he estimated in April.

The revised analysis left Scotland facing bigger losses and a longer recovery time before spending levels return to 2009-10 levels.
