First-cousin Marriage

Lord Kamall Excerpts

Monday 20th January 2025 Lords Chamber

[Baroness Merron (Lab)]

I certainly have not, and I am not aware of discussions that have taken place between Ministers or officials in our department and those in other countries. However, I will be very glad to look into that and to write to the noble Baroness.

[Lord Kamall (Con)]

My Lords, I thank my noble friend Lord Farmer for the Question, and the Minister for the sensitive way in which she is handling it. When we want to look at policy in sensitive areas, surely, we should be led by the data, so I just wonder what the Government’s latest data is. We know that about a decade ago, 6% of congenital defects or anomalies were in children born to first cousins in Pakistani communities, compared to 3% for the wider population. I have seen more recent statistics that say the figures are now 4% and 2%. So, what is the latest data the Government are working with, and what level would those congenital defects have to reach before they were seriously concerned?

[Baroness Merron (Lab)]

I thank the noble Lord for his support in this area, which is indeed sensitive. The statistics he quotes are quite right. It is of course an interesting reflection that the risk of genetic abnormalities does not just double from 3% to 6% in those infants whose parents are first cousins, but also doubles in older white British mothers—I am a bit worried about saying “older” because it is actually over 34. However, the point is well made that it is not just this group. NHS England has recently published guidance to improve the recording of national data on closely related couples, so I hope that noble Lords will find this of interest as we go along. But of course, there has also been much investment in research as well as data development, and I absolutely agree that data is what has to drive us.
