I agree with much of what the hon. Gentleman is saying and I, too, believe in purity, as long as I live in a pure world. I remind the hon. Gentleman—he might bear this in mind before developing his argument—that even some of our Commonwealth partners—for example, one of our historic markets in Australia—when in balance of payments trouble do not adopt devices of this kind but go further and close their ports against all imports of British goods. This has been done to the great detriment of the Lancashire textile industry on many occasions. I would like the hon. Gentleman's views on this.
