My Lords, I, too, have memories of motorways. The M25 went around the north of the constituency that I represented, in Enfield. The only tunnel constructed on the M25 was there, in order to protect the interests of my constituents. Subsequently there was an additional tunnel in order to protect a great deal of Epping Forest, which I also greatly supported. However, our negotiations and discussions were nothing to do with planning authorities; we had to deal with the Department of Transport and the excessive, terrifying costs of what is involved in tunnelling. That is why the M25 is a circular route 125 miles long but has only one tunnel, which is
constructed as far as the immediate neighbourhood’s interests are concerned. It was nothing to do with planning; the Department of Transport had to answer.
