Not obvious to me what point the UK locator form now serves, but happy to be told by someone in the know.
I am not sure what purpose it ever served, never mind about now when most restrictions have been abolished.
When I returned from France last November, the only check was from Eurostar staff to see that I actually had a form.
No-one checked the details on the form, especially the French and UK immigration staff.
I have seen reports that the UK passenger locator form will be abolished in time for the Easter holidays.
However that is over a month away, and there really is no need to wait that long.
The requirement to complete a PLF, as well as taking a COVID test, has been abolished for journeys starting in Russia or Ukraine.
There are obvious humanitarian reasons for this, as acceptance of refugees from the war in Ukraine is rightly seen as more important than worrying about whether they have COVID.
But if that is the case for Russia and Ukraine, then surely similar logic can be applied to everywhere else in the world, given that most adults in the UK have a good level of immunity from vaccination or previous infection.
