It is being reported that it was seeing those awful unhygienic pictures on the media in the middle of a pandemic that determined the French government's decision to stop the flow of trucks from British Ports.
I think that what is being referenced here is the recent pictures of pedestrianised London shopping streets completely chock a block with shoppers; very few of whom are wearing masks, when London has the fastest rate of spread in the UK and is closely associated with the mutant strain of c19.
Not a sight to fill surrounding nations, or, indeed, any nation, with confidence that the UK is doing all it can to stop the spread of the virus.
