I had a thread last month about the same thing but now we're in a March style lockdown I'm even more 
My DH is doing a business coaching course, they meet once a month when 20+ people come from all over the UK for a day together in a room with the business coach. It's hosted in London in the Hilton.
Last month I was very unhappy about it since London was in Tier 4 and it seemed totally irresponsible.
I really complained about it to DH who very reluctantly decided not to go (he sulked for a few hours). I'm not CEV but am in the 'more vulnerable' get a free flu jab group. We have a 66 year old lodger and we were meeting his parents in their 70s for Xmas the following week.
Anyway...we've gone into lockdown now, the case numbers are crazy, the new variant is spreading like wildfire. It didn't even cross my mind that it would go ahead in person this month.
DH has just informed me that it is going ahead next week.
That the Hilton have advised that it's perfectly legal to have a business meeting with 20+ people coming on public transport from all over the UK.
This seems fucking crazy.
I can't see that it's on the list of exceptions on the Govt website?
Can anyone find how this is supposedly legal?
Because I haven't reported anything but if this isn't legal I'm going to report it TBH.
