Experts have warned that the UK Government's immigration plans could reduce the number of workers in Scotland by up to 5% over the next two decades.

An advisory group, chaired by Professor Christina Boswell of the University of Edinburgh, was asked to advise the Scottish Government on migration, population growth and demographic change.

The group indicated that under the UK Government's White Paper, net migration to Scotland could be reduced by between one third and one half after 2020.

A salary threshold would be introduced, under which people earning less than £30,000 would not be allowed admittance to the UK - but it is estimated that 63% of workers in Scotland earn less than that.

The group also suggested the threshold would exclude a greater proportion of women than men, and younger workers.

Professor Boswell, said: "As the UK Government elaborates its proposals for immigration policy after Brexit, it is vital that we understand the effects of changes to migration on Scotland's economy and society.

"If the UK Government's proposals are enacted, we are likely to see a substantial fall in net migration to Scotland over the coming decades.

"But importantly, the effects of this reduction will vary across different sectors and local areas. The report considers the particular challenges for sectors reliant on non-UK workers who earn less than the proposed £30,000 threshold - such as accommodation and food services, manufacturing, and social care.

"It also considers the particular challenges for rural and remote communities, which are especially reliant on in-migration to sustain economic livelihoods and public services - but which will be most affected by the proposed salary threshold.

"The proposed transitional arrangements for short-term migration are also likely to lead to higher churn and integration challenges in local communities.

"We also find that the proposed changes would have gender impacts, potentially leading to a lower proportion of female migrants."

Migration Minister Ben Macpherson said: "The UK Government's focus on reducing immigration will damage Scotland and does not reflect the needs of our economy, our public services or our communities.

"The findings also reinforce the case for creating fair, tailor-made immigration solutions for Scotland that value all skills, work for businesses and support the delivery of public services across the country".
