TORY politicians have refused invitations to defend UK Government immigration proposals on The Nine, according to the BBC Scotland show's host.

Martin Geissler revealed on Twitter that despite contacting both the UK and Scottish parties, no Conservative politician said they are able or willing to appear on the flagship programme.

The host stated Scottish party leader Jackson Carlaw and Scottish Secretary Alister Jack had been approached, as well as Home Secretary Priti Patel.

Despite contacting several other high-profile Tory figures, as well as lower-ranking MPs and MSPs, none accepted the invitation.

The Scottish Conservatives, Home Office and Scotland Office have been approached for comment.

It comes after the UK Government unveiled proposals to stop providing visas to low-skilled migrant workers, instead outlining plans for a new points-based system.

A minimum salary threshold of £30,000 is to be set, which can be lowered to £25,600 for those coming to the UK with a job offer.

In June last year, Scottish Tory MPs and MSPs urged then-prime minister Theresa May to introduce a “flexible” system amid concerns a UK-wide approach could harm the Scottish economy.

Former Scottish Tory MP Kirstene Hair had said: “The next Prime Minister must be aware of the difficulties that a one-size fits all approach could cause for Scotland’s economy.

“It is clear that there are serious concerns about the £30,000 salary threshold for skilled workers in particular.

“That must be re-visited and other measures explored to ensure that the system continues to work for all parts of the UK.”

Although no such concession appears to have been made in the latest immigration plan, no Scottish Conservatives have spoken out against the plan.

Nicola Sturgeon warned the proposals will be “devastating” for Scotland and said gaining control of migration powers is a "necessity".

Scotland Food & Drink chief executive James Withers described the plans as “hugely worrying”.

Donald Macaskill, chief executive of Scottish Care, claimed UK ministers were "in cloud cuckoo land" while the Scottish Tourism Alliance branded the plans "the biggest threat to Scotland's tourism industry".

But Scotland Office Minister Douglas Ross claimed the proposals would be beneficial for Scotland.

He said: “The new system announced today will make sure our economy attracts and retains the best talent from around the world, welcoming people to Scotland and the whole UK based on how they can help grow our country."
