My hon. Friend mentions what happened last Friday afternoon. It is extraordinary that Parliament was closed down in the middle of the afternoon and our staff were sent home. I was with a party of schoolchildren who, ironically, were the chief debaters who had won a competition in the London boroughs, and were looking forward to their tour of Parliament. They were mainly black, Asian, and minority ethnic youngsters, including identifiably Muslim and Jewish children, who were then asked to leave the estate and filter out into the crowd. Is it not extraordinary that we can be brought to such lengths by a few extremists and thugs?
