I think restrictions are perfectly reasonable, but I think she should be explaining them as due to high volume of cases and/ or actual imported cases and/ or reciprocal measures. Identifying the issue as Delta variant is a red herring given that's already the leading variant and risks identifying EU growth as the "fault" of Spain / Greece for doing things differently, which doesn't look fair.
Fair point…I think the issue I have with a few posters is the idea Madame Markell is being uniquely awkward or unusually defensive when it comes border control.
Certainly right now if somebody living in certain EU countries wants to visit the UK (e.g. to see relatives) the big, big problem is the UKs Amber list restrictions, not the requirements on return to the EU.
