My Lords, if Gypsies and Travellers are not to camp illegally then, of course, authorised sites must be provided by local councils. After legislation was introduced some 50 years ago, there was a count of how many Traveller and Gypsy caravans there were in England, and the answer was 8,045. There are now 20,000 authorised sites, but 25,000 Traveller and Gypsy caravans. What is behind this increased demand for a nomadic Gypsy and Traveller lifestyle?
