Many Britons who reach retiring age decide to spend the rest of their lives overseas in the sun, and for many that means Portugal. There are around 60,000 Britons living in Portugal, not all of them retirees. Those who go there to work very often go to Lisbon, which is a somewhat more expensive place to live than other parts of the country, but a lot of people who don’t need to work choose the Algarve.
