Conservative MP Richard Holden is set to introduce the Marriage (Prohibited Degrees of Relationship) Bill in Parliament, sparking fresh discussions about the legal and ethical implications of such unions.
Understanding the Current Law
Under existing UK law, marriages between close family members such as siblings, parents, and children are prohibited under the Marriage Act 1949. The Sexual Offences Act 2003 also criminalises sexual relationships between these relatives. However, first-cousin marriages are currently permitted. If Holden’s proposal is approved, both these acts would need to be amended to include first cousins among prohibited relationships.
Why Ban First-Cousin Marriages?
One of the main reasons for the proposed ban is health-related. Studies indicate that children born to first-cousin couples are at a significantly higher risk of genetic disorders and birth defects. According to Holden, these marriages are linked to “approximately double the rate of birth defects compared to the general population.”
Beyond medical risks, Holden argues that first-cousin marriages can reinforce restrictive societal structures, particularly affecting women’s autonomy. He believes banning them would be a progressive step toward greater individual freedom and equality.
Cultural and Community Considerations
Holden highlights that first-cousin marriages are a cultural practice rather than a religious one, particularly in communities where the tradition remains common. Research by Dr. Patrick Nash suggests that between 38% and 59% of British Pakistanis marry their first cousins. Professor Alison Shaw of Oxford University has also noted that this trend may be increasing.
This proposed law follows previous efforts by Holden, including the successful ban on hymenoplasty and so-called virginity testing. He is now urging the UK government to align its marriage laws with other countries that have already prohibited first-cousin unions.
Government Response and Next Steps
The Labour Party has not yet taken a formal stance on the bill, stating that it requires time to “properly consider our marriage law.” Justice Minister Alex Davies-Jones acknowledged the complexities involved and indicated that the government would assess the broader legal framework before reaching a conclusion.
As Parliament debates the issue, key factors such as health risks, cultural traditions, and legal precedents will shape the outcome. If the bill is passed, it could mark a significant shift in the UK’s approach to marriage law.
