Reports in the national press over the weekend, citing government sources, suggest that Johnson could announce a long-anticipated "test and release" scheme on Monday (23 November).
Test and release would allow people returning from non-travel corridor destinations to come out of quarantine on their fifth day of self-isolation, providing they test negative for Covid-19.
It is understood the new quarantine measures will form part of the government’s new Covid winter plan, which Johnson is expected to outline on a Commons address on Monday afternoon.
