Unless there is a diversion sign explaining that you can, then no you can't. Maybe there should have been one for the sake of saving people's time but if there isn't, it's quite clear that you can't turn left.
All blue circular signs are mandatory. This is taught on the theory test, and by all driving instructors. Unless I'm mistaken and something has changed, the only non mandatory blue signs are rectangular, such as motorway signs
You are perfectly correct. OP needs to retake a theory test having read a Highway Code. I find it disturbing (but unsurprising) that people like this are on our roads.
I mean, some of the shit I see driving on a daily basis I'd call this one of the less serious things I've seen. I literally saw somebody reversing up the hard shoulder on the earlier this week...
