The National Health Service has come under intense criticism for publishing guidance that highlights the benefits of first-cousin marriages, despite well-documented health risks and concerns about women’s rights. The controversial guidance, released by NHS England’s Genomics Education Programme, has sparked outrage from politicians and experts who accuse the health service of prioritizing political correctness over public health.
The NHS guidance acknowledges that cousin marriages carry increased risks of birth defects but argues these unions offer significant social and economic advantages. According to the document, benefits include “stronger extended family support systems” and “economic advantages” where “resources, property and inheritance can be consolidated rather than diluted across households.”

Historical Context and Current Practice
The guidance points to historical precedent, noting that cousin marriage has been legal in Britain since Henry VIII’s reign in the 16th century. The Tudor king reportedly passed legislation enabling him to marry Catherine Howard, who was Anne Boleyn’s cousin, after breaking with Rome.
The practice remains common within certain communities, particularly among British Pakistanis. However, medical data reveals concerning patterns: up to 20 percent of children treated for congenital problems in major cities like Sheffield, Glasgow, and Birmingham are of Pakistani descent, despite representing only 4 percent of the wider population. The treatment costs for these genetic conditions place a significant financial burden on the NHS, running into billions of pounds.
Health Risks and Statistics
While the NHS guidance attempts to minimize the health risks, the statistics tell a sobering story. Children in the general population have a 2-3 percent chance of being born with genetic conditions. This risk doubles to 4-6 percent for children of first cousins. The practice has been specifically linked to higher rates of cystic fibrosis, sickle cell disease, and other serious genetic disorders.
The guidance compares cousin marriage to other risk factors such as advanced parental age, smoking, alcohol use, and assisted reproductive technologies, noting that none of these are banned in the UK. However, critics argue this comparison is misleading and fails to address the unique social pressures often associated with cousin marriages.
Political and Expert Response
Conservative MP Richard Holden has announced plans to legislate against first-cousin marriages, citing concerns about integration, women’s rights, and public health. “Our NHS should stop taking the knee to damaging and oppressive cultural practices,” Holden stated, adding that the Conservative Party views cousin marriage as both a health issue and a “back door to immigration.”
Holden criticized Labour leader Sir Keir Starmer for allegedly avoiding the issue, claiming he is “running scared of misogynistic community controllers and their quislings who appear in the form of cultural relativist obsessed sociology professors.”
Dr. Patrick Nash, director of the Pharos Foundation social science research group at Oxford, condemned the NHS guidance as “truly dismaying.” He argued that the document promotes cousin marriage while ignoring its connections to “honour violence, gender discrimination, multifarious forms of clan corruption, and the immense cost to the taxpayer.”
Nash went further, describing cousin marriage as “incest, plain and simple” and calling for an immediate ban. He criticized the NHS guidance as “deeply misleading” and demanded its retraction with a public apology.
Public Opinion and Policy Recommendations
Public sentiment appears strongly opposed to the practice. A YouGov poll conducted earlier this year found that three-quarters of Britons support banning first-cousin marriages, with only 9 percent believing current laws should remain unchanged.
Rather than supporting prohibition, the NHS guidance recommends alternative approaches including genetic counseling, awareness-raising initiatives, and public health campaigns. The document argues that banning the practice would “stigmatize certain communities and cultural traditions.”
The Broader Debate
The controversy highlights tensions between cultural sensitivity and public health policy in modern Britain. Critics argue that the NHS guidance prioritizes cultural relativism over women’s rights and child welfare, while supporters might contend that education and counseling represent more effective approaches than outright prohibition.
The debate also touches on broader issues of immigration, integration, and community practices within multicultural Britain. As the controversy continues, pressure is mounting on health authorities and policymakers to reconsider their approach to this sensitive but significant public health issue.
The NHS has yet to respond to calls for the guidance’s retraction, leaving the debate unresolved as communities, politicians, and health experts continue to grapple with balancing cultural sensitivity against public health imperatives.
