It’d probably be in East Sussex so Bexhill/St Leonards/Worthing/Eastbourne - no Portsmouth for me!
But yeah I either move with my folks and the dog, or buy my council house and continue to commute in to London. So London being cancelled would actually help me decide because it removes one reason to stay put!
If I didn’t hate the thought of being more than 90 mins away from my family I’d move to Manchester, Leeds or Edinburgh probably.
