Humza Yousaf has condemned plans considered by Tony Blair’s former Labour government to hold refugees on a Scottish island as “disparaging and divisive”.

The Scottish First Minister reacted to the proposals, released in files by the National Archives in London, first mooted by the former prime minister’s aides more than two decades ago.

The plans were drawn up in 2002 and could have seen asylum seekers placed on the Isle of Mull, in the Inner Hebrides.

It never came to fruition but the plans are topical more than 20 years later as the current Prime Minister, Rishi Sunak, pushes on with plans to send asylum seekers to Rwanda in an effort to crack down on small boats crossing the English channel.

Mr Yousaf said the plans showed both Labour and the Conservatives were using immigration as a “really dirty word”.

He told journalists in Glasgow on Friday: “It is disappointing that both Labour and the Conservatives, as these files have shown, have engaged in a race to the bottom when it comes to the issue of immigration.

“We should have a humane asylum system, a migration system that helps us to fill the vacancies that we have in this country because they (migrants) contribute more than they give.”

Mr Yousaf also claimed the comments about the Isle of Mull could be “disparaging” to islanders with the proposals treating rural Scotland as a dumping ground.

He said: “It’s also very disparaging to Scotland – and to those on the Isle of Mull or elsewhere – to suggest that, ‘well, let’s just fling people in the far reaches of the country and forget about them, and leave them there’.”

And he raised concerns that a potential incoming Labour government would look to “tweak” the plans.

Mr Yousaf said Sir Keir Starmer had failed to deliver a “wholesale rejection” of the Prime Minister’s Rwanda plans amid suggestions Labour’s alternative plans include “tweaks” such as processing asylum applications overseas.

Mr Yousaf added: “People on the ground, the public, take their lead from political leadership and if the political leadership is talking about migration as a dirty word, fanning the flames of that tension around migration, then it’s hardly surprising it becomes a divisive issue as opposed to actually looking at the issue from a common sense perspective.”
