We weren't told which "well known newspaper" but with a headline like that it's going to be The Express or The Mail; possibly The Sun.
Norway and Denmark have excluded Sweden from their travel bubble, for good reasons, and I understand that currently Spain isn't allowing quarantine free movement from Portugal. If for example the UK decided quarantine were lifted for Belgium, but for The Netherlands; or France but not Germany that could be seen as discriminatory and the EU would be quite correct in looking for some fairness. However despite the "well know newspaper's" protestations from what has been said on a "well know broadcaster's" news channel that isn't likely to be on the cards.
Stinks of EU bashing for EU bashing's sake - so nothing new there then.
