Where sites are provided they are not used, because they have to pay toward the services provided.

Maybe there are instances where that happens - but not round here. Our sites in Harlow are full, and there's been no problem about people being unwilling to pay to use them. (If there actually are sites which people are reluctant to use, I suspect there could be other factors involved, such as having been put in unpleasant and even dangerous places.)

In fact sites should always have more pitches than are needed at any one time, to allow for people who are still leading a travelling life.

Typically, where illegal sites have ben set up, this has been because of local authorities obstructing attempts to set up legal sites, on land purchased and owned by travellers.

Labour doesn't come out of this too well - all right, it was the Tories who in 1994 abolished the duty of local authorities to provide sites (as a kind of reward to the many local authorities which had for years ignored the law, without being penalised in any way). But Labour has been in power since 1997, and that was more than enough time to undo the harm done.
