Contribution
The hon. Member contributes so often to our debates in such a thoughtful way. He raises an important point about health, which I will develop. The health issues are of fundamental importance but, as I have said in my speech, there are broader societal concerns that mean this issue should be higher up the Government’s agenda more generally as well.
For unrelated parents, the Born in Bradford study found that around one in 40 children are born with serious birth defects. Among first cousins, that rises to roughly one in 15, even when controlling for poverty, education and maternal age. That is more than double the risk. It cannot be stressed enough that this is not an isolated issue. In some communities, cousin marriage remains par for the course—the typical, not the atypical. In parts of Bradford, for instance, over half of all mothers of Pakistani heritage are married to first or second cousins.
That is hardly new information; as far back as the 19th century, the British Medical Journal documented inherited risks from unions between first cousins. Charles Darwin himself was married to his first cousin, and he suspected a link between his marriage and the poor health of his children, three of whom died young and five of whom suffered from chronic illnesses or disability.
The genetic risks run from the well-known Tay-Sachs, thalassaemia and cystic fibrosis to the under-recognised microcephaly, heart defects and intellectual disabilities. Those disorders are often lifelong, and the toll is felt not just by families, but by wider society—by the NHS, by our special educational needs system and across communities.
Alison Shaw, professor of social anthropology at Oxford, has written extensively on cousin marriage in British-Pakistani communities. Drawing on public health data, she highlights that children born to first cousins face roughly double the risk of serious genetic disorders compared with those of unrelated parents. Some have suggested that genetic testing could solve the problem but, while certain conditions can be screened for, many cannot. More importantly, testing does nothing to address the broader issues I have already spoken of around coercion and lack of real choice.
Moreover, as UK Biobank studies demonstrate, multi-generational first cousin marriages exponentially compound risk. The DNA profiles in such families begin almost to mirror those of siblings, or certainly uncle-niece relationships, which often carry much higher risks of severe birth defects, when first cousin marriage occurs generation after generation. In broader culture, people often think of the Habsburgs as a reference point, but this issue is more than mere historical curiosity; it is sadly representative of a contemporary crisis that continues to affect families today.
Behind every statistic lie families, clinicians and patients struggling to manage lifelong consequences. What makes this more painful is that so many of these conditions are entirely preventable. When the science is clear, it beggars belief that we still choose not to do anything. We must stop pretending that this is a marginal issue. The data is clear: it is not anecdotal, but systematic. The status quo is not neutral; it is a form of abandonment, and sustaining it is indefensible.
If we were to design a system that throttled personal freedom, threw in major health issues and undermined national cohesion, we could hardly do better than the widespread practice of first cousin marriage. We ban incest for good reasons. We recognise the power imbalances inherent to sexual relationships between teachers and pupils, doctors and patients, uncles and aunts and their nieces and nephews, and parents and their children. We legislate to protect the vulnerable, so why are we silent here? Sadly, I fear that it is because we fear being called intolerant and it is sometimes easier not to look. The truth is that inaction is not neutrality; it is complicity. We must do better.
We need only to look at what has happened in recent days with the release of the report on grooming gangs. I think back to the Labour MPs who raised that issue at a much earlier stage, such as Ann Cryer, who spoke passionately about it almost two decades ago. There is a lot to learn from people who have gone before us.
My Bill currently sits before the House. I thank the Members who have already put their names to it, including the hon. Member for Liverpool Walton (Dan Carden), my right hon. Friends the Members for East Surrey (Claire Coutinho) and for Newark (Robert Jenrick), the hon. Member for North Northumberland (David Smith), my hon. Friend the Member for Harborough, Oadby and Wigston (Neil O’Brien), the hon. Member for Ashfield (Lee Anderson), my hon. Friends the Members for Fylde (Mr Snowden), for Berwickshire, Roxburgh and Selkirk (John Lamont), for West Suffolk (Nick Timothy) and for Weald of Kent (Katie Lam), and my right hon. Friend the Member for Sevenoaks (Laura Trott).
I urge the Government to take this matter seriously and to listen to the survivors, to professionals and to the silent majorities in the affected communities. We must stop treating such issues as a taboo. If the so-called community leaders had got their way, we would have kept marriage under 16 and we would not have banned hymenoplasty and virginity testing or people being taken abroad for forced marriage. This should not be a taboo issue; it is a public health issue. It is about liberty and integration.
The aim is not to condemn, but to liberate, in order to ensure that our country is one where freedom does not end at the edge of tradition, where cohesion is built on our common citizenship, not inherited constraint, and where children are not born into suffering that we have the power to prevent. We have a chance to take a lead and make a statement that in 21st century Britain, freedom, health and integration matter. I hope the Minister will hear that call.
