We have had a valuable debate. It is useful that the House should turn its attention repeatedly to the question of international trading arrangements. We should always be seeking to find the best means of meeting Britain's interests and it is in this spirit that I approach the subject. The idea of N.A.F.T.A. is not new and has a long history. I can recall in the mid-1950s discussing this with Senator Javits, in the context of N.A.T.O. being something other than a military alliance. The dialogue has continued ever since.
