Stepping off the train in Crawley, 30 miles south of London, you hear less English and more Romanian, Estonian, Portuguese and Polish.
Crawley is an affordable place to live, if less scenic than some other English towns. Other than a medieval church and old stagecoach inn, most of Crawley was built after World War II, to house people displaced by bombing in London. More recently, many immigrants have settled here and work at Gatwick Airport nearby.
Brexit has many of them worried. It's still unclear how many people from the European Union will be allowed to stay.
