A controversial proposal to ban first-cousin marriages has been introduced in the UK Parliament by Conservative MP Richard Holden. Citing public health concerns, Holden argued the practice increases the risk of birth defects and undermines societal values. However, the initiative has sparked a heated debate, with opponents advocating education over legislation.
Richard Holden, MP for Basildon and Billericay, presented the bill under the 10-minute rule, a parliamentary procedure allowing MPs to propose new legislation. Holden emphasized research showing that children of first-cousin unions face double the risk of serious genetic disorders compared to children of unrelated parents. He pointed to certain diaspora communities, including Irish Travellers and British Pakistanis, where such marriages are particularly prevalent, with rates ranging from 20-40%.
“The practice threatens women’s freedom and is not conducive to modern British society,” Holden argued. He linked the issue to strict honour codes, which he claimed restrict individuality and perpetuate social isolation or even violence against women.
Independent MP Iqbal Mohamed, representing Dewsbury and Batley, countered that banning first-cousin marriages would be ineffective and culturally insensitive. Instead, he advocated for health education programs and genetic testing initiatives to address the risks without stigmatizing communities.
“The way to address this issue is not through legislation but by raising awareness,” Mohamed said. He suggested providing advanced genetic screenings for couples and expanding cultural outreach efforts. Mohamed warned that a ban could alienate affected communities and fail to protect women forced into such marriages.
Downing Street acknowledged the health risks associated with first-cousin marriages but confirmed there are no current plans to alter the law. A No 10 spokesperson stated, “The government has set out its priorities, and changes to marriage legislation are not included.”
Holden’s proposal faces significant hurdles. Bills introduced under the 10-minute rule rarely pass without government backing due to limited parliamentary time. Meanwhile, the UK currently prohibits marriage between siblings, parents, or children, but first-cousin unions remain legal.
The debate highlights tensions between public health priorities and cultural traditions, raising questions about the best way to address genetic risks while respecting individual freedoms.
