On a point of order, Madam Speaker. I wish to raise a matter about which I have given notice to you and, by telephone and letter, to the hon. Gentleman involved. Last week, I received a letter from the hon. Member for Stafford (Mr. Cash), threatening me with legal action arising out of a speech that I made in the House 10 days ago, when I suggested or argued that he and other right hon. and hon. Members supported policies that would lead to the detachment or withdrawal of Britain from Europe. He now threatens me with legal action if I repeat those remarks. In no way did I question his personal honour, probity or integrity. I myself have been accused of being a Euro-federalist, which is a lie. Madam Speaker, is it in order for one hon. Member to threaten another with legal action on an important area of public policy debate?
