Health officials are trying to trace one person in England who has been infected with a concerning variant of coronavirus first found in Brazil.
They are one of six cases of the P1 variant found in the UK in February.
The person did not complete a test registration form so remains unidentified – prompting an appeal for anyone without a result from a test on 12 or 13 February to come forward.
Labour said there had been a lack of a “comprehensive” border system.
The P1 variant was first detected in travellers to Japan from Manaus in northern Brazil in January.
Health Secretary Matt Hancock will hold a meeting later to update MPs from all parties about the variant.
Dr Susan Hopkins, from Public Health England (PHE), says the UK was more advanced than many other countries at identifying the variants and mutations, and therefore was able to act quickly.
Holyrood said the three people tested positive while self-isolating. Other passengers who were on the same flight to Aberdeen are now being contacted.
