In the regulations updated on November 30th, Scotland emits a document which explains some rules for entering the country, named regulation 14, from which I copy an extract:
(9) The requirements of this regulation are that—
(a)the test is provided by a public provider, or where P is [F2not a red] list arrival, a public provider or a private provider, and [F3(b)the test is a test which complies with paragraph (9A)]
And this is from the main site, and you can find it almost anywhere else:
You cannot use an NHS test for your PCR test. You must use a private test provider.
Is this a contradiction between the law and the way they enforce it?
