What about inbound international travelers (not UK residents)? I didn't get anything from the press conf that would clarify that. What if I'm visiting friends / family in the UK, quarantining with them for the duration of my stay, and then departing? Not sure if that falls into "leisure". Could also argue that then departing the UK is "essential" in a sense as I'd need to get home and don't want to be stranded there. Need to see exact wording of these regulations as I have a trip to London planned for next weekend...
