Water Quality: Sewage Discharge

On a point of order, Mr Deputy Speaker. A little while ago, when Peter Tatchell came to visit me, he had a badge confiscated from him—a campaigning badge against homophobia. I subsequently received a letter of apology from the Serjeant at Arms saying that he would look at that practice. Yesterday, some other people came to visit me. They had a series of leaflets about the Chinese Government’s treatment of Jimmy Lai, and those were confiscated too. There may well be a well-intentioned purpose behind this, but will the House authorities look at the operation of these rules, because it seems very odd that it is illegal to bring political material into the House of Commons.
