Four friends in their early 20s (two households in London) have been planning a short holiday starting tomorrow. The plan was to leave London after work tomorrow, travel together on the first stage of their journey, stay overnight, and then continue their journey first thing on Saturday morning.
When they leave London, it will be in tier 1. By the time they leave the first stop on Saturday morning (also in tier 1), the tier 2 restrictions will have come into force in London, which means no mixing of households indoors. But mixing of households is allowed in the tier 1 area where they will be by then. They will stay in tier 1 areas for the remainder of their break, until returning separately to their tier 2 London addresses.
I am not clear whether they are bound by the tier 2 restrictions if they have left London before they come into force.
It doesn't make any difference legally, I know, but their area of London has an infection rate below the national average. On the one hand, it doesn't seem quite right. On the other hand, if they had already left London presumably they wouldn't need to go home.
I'd be interested to hear what people think. Thanks.
