In a speech in the House of Commons David Cameron paid tribute to the security services and also vowed that the government will not stand for extremists or, "groups like the English Defence League who try to demonise Islam and try and stoke up anti-Muslim hatred."

Already this year there have been three major counter terror trials in which 18 people were found guilty and sentenced to a total of 150 years in prison much more of the British security services necessarily goes unreported. They are Britain's silent heroes and heroines and the whole country owes them an enormous debt of gratitude.
Just as we will not stand for those who pervert Islam to preach extremism, neither will we stand for groups like the English Defence League who try to demonise Islam and try and stoke up anti-Muslim hatred by bringing disorder and violence to our towns and cities.
