The SNP has been accused of a “total lack of vision” as it unveiled new measures aimed at boosting Scotland’s economy.

Finance Secretary Derek Mackay said his new economic action plan – which includes an £18 million fund for advanced manufacturing – would help drive growth.

But critics said it missed a series of “open goals” and fails to address Scotland’s under-performance.

It came as Mr Mackay insisted his “door is open to any party” as he prepares to outline his Budget proposals in December.

The minority SNP Government has recently relied on the Scottish Greens to help push through its spending plans, but the party has refused to enter talks this year unless progress is made on overhauling local tax.

Mr Mackay said new economic measures include maintaining a “stable and competitive” tax regime, as well as launching a campaign aimed at attracting overseas workers in the wake of Brexit.

He said: “Scotland has huge economic potential and we are well placed to take advantage of the economic opportunities that come from our established strengths in innovation and technological change.

“That will stimulate our economy even further, and lead to a more prosperous and fairer society.”

But Scottish Conservative shadow economy secretary Dean Lockhart said it was “just another example of serial economic failure from the SNP”.

He said: “Today’s announcement from the SNP highlights a total lack of vision with no new policies or even targets for Scotland’s economic performance.”

Scottish Liberal Democrat leader Willie Rennie said: "This plan misses a series of open goals.

“Every year a million days are lost to business from mental health-related absences yet there is nothing in this plan about addressing this challenge.”

Retail leaders welcomed many of the announcements, but called on the Government to do more to deliver a competitive tax regime for businesses.

Mr Mackay said his door was open to any party to ensure his Budget passes through Holyrood next year.

However he appeared to dismiss a recent offer from the Scottish Tories, arguing they were “focused on tax cuts for the richest”.

He said the Government was “engaging” with local authority leaders over plans to allow them to levy a tourist tax.

He said: “In terms of the transient visitor levy, or tourist tax, we’ve said we’ll hold roundtables. So we’re engaging on that issue.

“As a Government we still have no plans for such a tax, but we are engaging with the sector, with local government.”
