I've come from a country were cousin marriage and indeed marriage to any close relative if illegal.
I've recently started working in a dialysis unit and I'm so disturbed by how many parents are young children born of first cousin marriage. Usually from South Asian backgrounds.
Today I was speaking to one parents who has 9 children, all in need of kidney transplants. The eldest 2 have already had theirs. Parents are first degree cousins and each have various medical problems of their own.
Why, as a society, do we allow these marriages? It seems so cruel to the children who are born with medical and genetic problems.
Maybe I'm easily shocked, I don't know.

Irish travellers have high levels of cousin marriage too. In Ireland something like 2 in every 5 traveller marriages are cousin marriages with up to 70% involving some form of consanguinity, I'd imagine it's the same in the UK.

These things are so engrained into some cultures that just banning it isn't going to work. Like someone else said perhaps more information and encouragement around genetic testing is the way forward. People won't put themselves forward though if it is shrouded in shame, open conversations need to be had but there is no reason that it can't be done from a place of education rather than 'eww gross, cousin marriage'.

Do travellers see a lot of resulting genetic conditions?

I haven’t called anyone racist? I genuinely don’t know what you’re on about.

So what exactly is “Hmm…Iqbal Mohamed. Funny that isn’t it?” about?

And who told who they were racist because I’m still not seeing it in the quote you included.

FairKoala · 26/01/2026 21:44

It was so very sad to see children suffering from something so preventable. Its been a while since I watched the documentary, but if memory serves a lot of the marriages were because they didn't want to dilute their genetics with outsiders and there was dowry issues etc

How does that work if the children from these unions end up being so profoundly disabled they can never be in a position to have their own children and the “blood line” ends

I'm in the US, so I don't super pay attention, but I did read an article within the past week or two that someone from the NHS was telling midwives that there are benefits to first cousin marriage and that the drawbacks are not so bad. I'll see if I can find the article.

I think you'll find that those findings had a little agenda all of their very own!

HarvestMouseandGoldenCups · 26/01/2026 21:46

Yes it’s becoming a real issue in some parts. But some cultures believe that God decides whether the children of such marriages are sick or not.

I do think first cousin marriage should be outlawed, with marriages prior to the ban remaining legal of course. But people don’t want to touch the issue.

ffsnewusername · 26/01/2026 21:47

It’s awful but very cultural. It destroys lives and costs a heck of a lot of money from the taxpayer.

This is what Iqbal Mohamed said during the debate tabled by Holden:

As the right hon. Member for Basildon and Billericay (Mr Holden) states, there are documented health risks with first-cousin marriage, and I agree that there is a need for greater awareness about that issue. Virginity testing and forced marriages must be prevented, and the freedom of women must be protected at all times.

However, the way to redress the issue is not to empower the state to ban adults from marrying each other, not least because I do not think such measures would be effective or enforceable. Instead, the matter needs to be approached as a health awareness issue and, where women are being forced against their will to undergo marriage, as a cultural awareness issue. In doing so, it is important to recognise that this is a highly sensitive issue for many people. In discussing it, we should try to step into the shoes of those who perhaps are not from the same culture as ours, to better understand why the practice continues to be so widespread.

An estimated 35% to 50% of all sub-Saharan African populations either prefer or accept cousin marriage, and it is extremely common in the middle east and south Asia. The reason the practice is so common is that ordinary people see family intermarriage as something that is very positive overall; as something that helps to build family bonds and puts families on a more secure financial foothold.

However, as is well documented, it is not without health risks for the children of those relationships, some of whom will be born out of wedlock. Instead of stigmatising those who are in cousin marriages, or those who are inclined to be, a much more positive approach would be to facilitate advanced genetic test screening for prospective married couples, as is the case in all Arab countries in the Persian gulf, and to run health education programmes targeting those communities where the practice is most common.

I therefore urge the House to vote against the motion and to find a more positive approach to addressing the issues that are caused by first-cousin marriage, including the health risks, and the consequences of modern conflicts and displacement of populations around the world.

Yes and it’s bollocks because you can’t reliably screen for inbreeding related disabilities

zeddybrek · 26/01/2026 21:50

I did work experience at a GP practice in 1997 when I was 16. At the time, a very long document was shared with the practice detailing the increased risks of genetic disorders for children of cousin marriages and the studies to prove it. I read the whole report as it was fascinating at the time to see the evidence. It's such a shame that knowing that nothing was done. I'm of South Asian heritage and feel it should be made illegal. In nearly 30 years nothing has changed. Make it illegal and it will make people think twice. Those poor children that have to suffer because of their parents lack of education. We are so scared to criticise anyone even if they are doing something wrong.

Burntt · 26/01/2026 21:50

I don’t think education will help the women who are not given much choice. Not do the men have much choice often.

i work in early years SEND education and it’s well known and covered anecdotally in a lot of training. Rarely is it in the actual presentation or textbook. People are scared of being called racist. But it’s obvious when the first MAKATON signs for foods are culturally not British and are taught in levels 1&2 and the British foods don’t come in till later levels.

However I do agree with a pp who said where do we draw the line allowing people to marry when we kown there is a higher likelihood of inheriting problems. When does that become stoping groups of people having children?

I have been told that in Iceland you can get an app so that when you meet someone super in a bar, you can quickly find out how you are related to him or her before starting to date.

Iceland was presumably aware there was a problem with everyone being related to everyone else to some degree!

Yup, I was told truth: https://supertravelr.com/en/trip/iceland/iceland-is-so-small-theres-an-app-that-keeps-icelanders-from-dating-their-relatives-B8D7BFDAF9/

It’s like wading through custard.

You made a point. I asked you to clarify your point. You pretended not to know what I’m talking about and attempted to deflect. I asked you to clarify your original point. And now you’re deflecting again. It’s almost as if…you don’t know what you’re talking about.

This gives me hope but change is so slow. I'm very happy you and your cousin made the right choice for your future happiness and more importantly future children.

Thank you. Yes, it is slow. But to reassure you further, my cousin is actually a Doctor now and working in the NHS. He is staunchly against first cousin marriage and advocates against it regularly within the community and is not alone.

I didn't mention but we are from Bradford. Therefore, we have a full lived experience of the devastation this can cause to young children who are born with genetic disorders stemming from multiple generations of cousin marriage. All to soothe egos of the elders who thought 'better the devil you know' and who want their own to take care of them when they are old.

It was over fifteen years ago, when we were told to get married and we refused. The fallout was tough but bearable.

The upcoming generation have a lot more backbone then my generation did and I think thats because of the options that come with their education, the fact that it is much harder to force someone to marry these days and the education authorities now have regarding these issues.

It’s probably relatively common to have a teen crush on a cousin. People are often drawn to people who look similar to them as romantic partners.

That makes me feel a bit better, thanks 🤣

My friend works in genetic testing in a major city hospital. It's the biggest cause of birth defects they see.

It's the biggest cause of SEND presenting children in schools. In areas where there's no demographic that favours first cousin marriage there are far fewer children who are compromised. In areas like Bradford, Birmingham etc it's a massive problem

Simplelobsterhat · 26/01/2026 21:54

PrizedPickledPopcorn · 26/01/2026 21:06

Individual cousin marriages aren’t that problematic. The issue leading to all the disabilities is repeated cousin marriages so that individuals are effectively far more closely related.

And the reason bans aren’t being pursued is the teams working there feel it’s already declining as a result of education. If it’s banned, it’s likely those arranging the marriages will simply pursue religious marriage without civil marriage, leaving the women in particular very vulnerable. Continuing with education ensures all involved get good medical advice and care.

That makes a lot of sense as a reason not to ban.

However I do think legal changes can help as well. Everyone knew smoking and passive smoking was bad for you before the smoking ban, but it really dropped after that, and became a lot easier to object to people smoking / less socially acceptable to smoke publicly. I wonder whether legal changes as well as education would make it easier for people to push back in their own families / community.

Umm I don’t think it is just people who are “shipped over” as you so delightfully put it. Wasn’t it quite common in the royal family too until very recently? Queen Elizabeth II was third cousins with Phillip. Queen Victoria was first cousins with Albert. I’m sure there are many more lesser royals too.

Funnily enough nearly 200 years later, we have learnt a lot about genetics. Amazing!!
