My Lords, throughout my political life I have always supported the right to peaceful protest, but the marches that have taken place in London, particularly during the past two Saturdays, supporting the Palestinian cause, have clearly been hijacked by hostile groups, chanting dreadful things, as the noble Baroness noted, along with calls for jihad. It was obvious to anyone that this would happen. Could my noble friend the Leader please find out who signed off on these marches and whether there will be another one this coming Saturday?
