From a BBC report:
The number of people approaching Shariah Councils and the number of Shariah Councils themselves are increasing. Of course the BBC report focuses on the disease part called injustice to women in Islam but the truth is difficult to circumvent. And the future, Lord willing, is bright:Sharia has been operating in the UK, managed by locally-appointed councils, in parallel to the British legal system since 1982.But the informal councils have no legal powers and they cannot impose any penalties.
They deal with civil cases alone, but many Muslims are choosing to voluntarily accept rulings made by the scholars.
As a demand for Sharia thrives, a number of British law firms are starting to tap into the booming market.
