Time Traveller
The days not counting used to be the case. It changed last year due to a high court ruling. Days travelling to the UK now count in full. So if you travel to the UK friday night and leave monday morning that was 2 days, now 4!
Completely out of step with the rest of the world. But the rest of the world doesn't have such deplorable government!
The domicile/residence rules have also changed in their favour to such an extent that any property, family at school, business etc. in the UK could be contrued as your centre of existance. Full tax again!
The only way in my opinion is to get off the ship altogether and live in a fair country. Something the UK under GB most certainly is not!
