My hon. Friend is quite right. That is why Albert Owen has a fair point. Some people will be able to afford permanent housing, thereby further pressurising the housing market in areas where such housing is limited. Static caravan parks have been a perfect arrangement, because they allow both the local community and people from outside to benefit. They have meant that the local worker who is looking for a house—often someone who works at a caravan park—has been better able to find a house.
