A legal expert says that thousands of Muslims marriages conducted in the UK are not legal.

Aina Khan, Head of the Islamic Law Department at Duncan Lewis Solicitors told BBC's Inside Out.

“I have found in my work, that more than 80% of Muslim marriages conducted in the UK are not registered, that is they are not legal under English law.”

Aina was speaking as part of a documentary exploring the issue of “thousands of British Muslim women discovering that their marriages are not legal.”

It is claimed that the problem is directly related to the fact that 90% of mosques are not registered to perform marriages.

Aina will be launching a series of nationwide road shows in the coming months, as well as a unique survey to gather data on the number of Muslim marriages that are not registered under UK law.
