So he lived in Tenerife and didn’t pay either tax or national insurance in the U.K.?
Now, when he decides to retire, he plans to return to the U.K. and wants to know what he is entitled to! Sorry, but morally I think people like this should get nothing and I really hope that nothing is what he is entitled to.
Why should people like myself, who have paid their dues in this country, support someone who has decided to live abroad most of their working life?
