The major development, however, has been the encroachment of Sharia law into public life. Last February, the Archbishop of Canterbury, Dr Rowan Williams, declared that British Sharia was "inevitable." In fact, instruments for expanding it already exist. A network of Muslim Arbitration Tribunals (MATs) has been set up with Home Office support. In theory, these bodies are just a form of "alternative dispute resolution". They are "unable to deal with criminal offences", says the MAT website. Yet it also confirms that they can "assist" the police with domestic violence, sometimes "with a view to reconsidering criminal charges".
