People are sleeping rough for a range of reasons because of successive UK Government policies.

People are sleeping rough because of UK Government policy.

I agree with this, though a friend of mine does some work with homeless people in Cardiff. He reckons there's enough space to give them shelter, just that many feel safer on the streets than in shelters. He reckons most of them avoid the Huggard Centre (as one example) because of fears for their own safety.

Solving the causes of homelessness should be a bigger priority than trying to provide for people who are homeless. As rs3100 rightly points out in his list, there are a number of causes. Reducing wealth inequality would certainly help as well.
