Via the BBC (h/t Islam in Britain):
An estimated 85 Sharia councils could be operating in Britain, according to a 2009 report by the think tank Civitas.
Several bodies like the Islamic Sharia Council have seen a large increase in their cases in the past five years.
''Our cases have easily more than tripled over the past three to five years," says Sheikh al-Haddad.
''On average, every month we can deal with anything from 200 to 300 cases. A few years ago it was just a small fraction of that.
''Muslims are becoming more aligned with their faith and more aware of what we are offering them,'' he explained.
