According to MmeBB, ZG said (I presume she is quoting him):
'In fact I have always been resident in the UK, and have always chosen to be tax resident in the UK. I therefore haven?t merely paid tax on UK income ? but on income generally ? at the full rate. Non-dom status can mean many things. Through my choices, it offered me little benefit, a fact that has been confirmed in writing by PricewaterhouseCoopers.'
Utter tosh. This is what the BBC has to say about what non-dom status means:
"At the moment people with links abroad, but living in the UK can declare another country as their real home, or "domicile", regardless of where they actually reside.
As a result they pay no UK tax on their earnings or capital gains outside the UK.
This has encouraged many rich foreign businesspeople to live in the UK.
Greek shipping tycoons, Saudi princes and American bankers have all taken advantage of the laws.
Few other countries have such a loophole.
Most, like the United States, insist that if you live in the country you have to pay taxes on your worldwide earnings."
So if you are going to be a British MP, then your domicile should surely be the UK?
And I think the bit about the US is relevant to the OP too. You wouldn't get away with it in your country so why the hell do you want people to get away with that kind of crappy tax evasion in ours?
