On a point of order, Mr. Speaker. Will you give guidance to the House in regard to the calling of speakers? On previous occasions when the matter was raised, you said that you would call a speaker from the Liberal Benches and from the SDP Benches, and on many occasions you treat them separately in debates. Can you give any guidance about what will happen under the new situation, whatever that may be? How will the group of the right hon. Member for Plymouth, Devonport (Dr. Owen), which is quite separate and refused to merge, be allocated time?
