On Sunday, France (whose Muslim population is three times larger than Britain’s) summarily deported to his native Algeria the cleric Abdelhamid Aissaoui for preaching extremism at a mosque in Lyon. He is the 11th such cleric to be expelled by the French Government in the past three years.

Interior Minister Nicolas Sarkozy didn’t mince words: ‘We will not keep people on our territory who issue calls to hatred, to violence and to the disrespect of our democratic values. They will leave the territory and they will leave quickly. In this area, we don’t intend to tolerate anything.’

As the shock of July 7 wears off, people will rightly start to ask angry questions about what has happened to a country that has lost control of its borders over the past 20 years. Our politicians – and our judges – will need to start listening.
