Spain has now followed suit by banning travellers from the UK except Spanish nationals and residents.
The measures adopted by Spain and Portugal are those that the EU seems to want generalised, rather than the total travel bans that some countries instituted.
In any case, the new measures in France are that travel is open with the UK for freight and for French nationals and residents of France & other EU countries (which would include UK and other non-EU nationals resident in those places) after a negative Covid test, which is close to what Spain had decided -- except that there are also general travel bans in much of the UK "
apart from limited exceptions, such as work purposes" (UK government information), so virtually no travel involving the UK except for people returning home or for work purposes etc.
So not much good news at all for pilgrims, though it might be well to repeat that the French routes or French sections of the major routes have become feasible again since December 15th for those able to travel to France, bearing in mind the 8PM-6AM curfew and that all bars are closed and only takeaway restaurants are functioning -- it's probably the only European country where a longer
Camino of some sort is presently possible again, as the situation in Italy is overly touch-and-go.
Whilst Italy is in regional lockdown 'til January 6th included, the situation in the locked-down regions such a Lombardy and Piemonte (including a long section of the
Francigena) seems to be improving with some restrictions relaxed (outside of the Christmas season national lockdown), but local lockdowns could still pop up anywhere in Italy overnight like toadstools.
