Marriage: Relatives

Asked by Dr Luke EvansConservativeDepartment of Health and Social CareTabled Answered 8 September 2026UIN 21877

The question

To ask the Secretary of State for Justice, if he will introduce measures to progress changes to the Marriage Act 1949 and the Sexual Offences Act 2003 to place restrictions on first cousin marriage.

Answered by Department of Health and Social Care

The Government does not collect data on the prevalence of first cousin marriage. The evidence referenced in WPQ 16079 relates to longitudinal research from the Born in Bradford programme which shows that rates of consanguineous relationships have fallen substantially over time.

As a matter of course, officials at the Ministry of Justice and the Department for Health and Social Care work collaboratively on the topic of cousin marriage, including on the risk of congenital birth defects posed to children of closely related parents.

We recognise the serious concerns that have been raised on this issue. As any responsible Government would do, we will be considering all options on how to tackle first cousin marriage.
