Read the article and it tells you.
Do you calculate a different figure? What is it, and how did you calculate it?
JohnD I did read the article, It's full of conjecture. " The UK may get this," It might well get a better agreement than Lord Rose proposes. He goes on to "predict" that any break up with the EU will be "acrimonious" (without stating why) So it's only his conjecture.. Anyway, he's a Lord, so his pension is already taken care of, before mine or yours.
Do you think for one minute that a split with the EU will affect his income?? I can't see him "downsizing into a two bedroom bungalow,,, Can you? (and he won't be driving round in a Kia Picanto anytime soon)
