Colleague of mine has just holidayed in Croatia with her family and had a lovely time. She got back a week last Saturday (they changed the rules on Croatia and returnees having to isolate in the UK 6 days into her 15 day hols) and is allowed out at 10.00 this coming Saturday night.
She didn't have to isolate in Croatia a month ago so if it's changed it's been in the last 3 weeks.
