My hon. Friend has made an excellent point. I think that what we can do, through the words that we use, the speeches we make and the debates that we have in the House, is set the context for confrontation of not just the violent extremism, but the extremism and poisonous ideology on which these people thrive. However, it we must be made clear that in too many cases we have home-grown extremists: people
who were born and bred here, and then radicalised here. Of course we must do more to kick out the preachers of hate and people who do not have the right to be here, but we have our own domestic, home-grown problem to deal with as well.
