Is my right hon. Friend aware that the Caravan Sites Act 1968 and section 39 of the Public Order Act 1986 are now quite inadequate to deal with the growing problem of travellers in many constituencies, as my hon. Friend the Member for Dartford (Mr. Dunn) mentioned earlier? May we have an urgent debate on this subject next week to discuss ways in which these two pieces of legislation may be strengthened and whether we should introduce a new criminal offence of aggravated trespass?
