On a point of order. My hon. Friend the Member for Sheffield, Park (Mr. Mulley), was called and had started to speak when my right hon. Friend was called, with your permission, and allowed to interrupt the speech of my hon. Friend, who then sat down as a matter of courtesy. [HON. MEMBERS: "No."] Perhaps I might be permitted, in ordinary courtesy, to put a point of order to the Chair. My hon. Friend had to sit down when you rose and allowed my right hon. Friend to interrupt. Therefore, the right hon. Gentleman was interrupting the speech of my hon. Friend, which was already in progress, with your permission and under your Ruling. My hon. Friend had the Floor subject to that interruption at your discretion.
