And the practise is also currently on the decline. https://en.wikipedia.org/wiki/British_Pakistanis#Consanguineous_marriage_and_genetic_risk https://en.wikipedia.org/wiki/British_Pakistanis#Consanguine... https://en.wikipedia.org/wiki/British_Mirpuris#Endogamy_and_kinship https://en.wikipedia.org/wiki/British_Mirpuris#Endogamy_and_... The irony is, of course, that this law is being proposed while the NHS has been advised (by a quango, not the government) to stop discouraging cousin-marriage: https://www.thetimes.com/uk/healthcare/article/first-cousin-marriages-nhs-advice-6c2j6sbmz https://www.thetimes.com/uk/healthcare/article/first-cousin-... -- the NHS is not required to accept this advice, and indeed the links above show that cosanguinity is decreasing, partly because of public health initiatives telling people what the harms are!
