'Sharia is incompatible with the fundamental principles of democracy'

That sharia is incompatible with the fundamental principles of democracy is not just my view but that of the European Court of Human Rights.

In the case of Refah Partisi v Turkey, the ECHR upheld the Turkish Constitutional Court's dissolution of The Welfare Party (Refah Partisi) for violating Turkey's principle of secularism (by calling for the re-introduction of religious law). The ECHR held "that sharia is incompatible with the fundamental principles of democracy."

The ECHR justified this by reasoning that a legal regime based on sharia would diverge from the Convention's values, "particularly with regard to its criminal law and criminal procedure, its rules on the status of women and the way it intervenes in all spheres of private and public life in accordance with religious precepts."

Yet the British establishment seem more and more intent on accomodating sharia law in the UK, why?
