First-cousin marriages has ‘benefits’, says NHS guidance despite birth defect risk
NHS guidance was withdrawn after praise for first-cousin marriage sparked backlash over increased genetic risks and costs, with up to 20% of congenital cases in some cities linked to this practice.
- Last week, NHS England's Genomics Education Programme published an article asking whether first-cousin marriage should be banned, but it was removed after backlash and the NHS later apologised.
- Framing the debate historically, the report noted first-cousin marriage has been legal since the 1500s and cited benefits like stronger family support and economic advantages.

- Conservative MP Richard Holden pressed his bill to ban first-cousin marriages, which returned to the Commons last week ahead of a second reading early next year, while Wes Streeting, British Health Secretary, demanded an apology over NHS guidance.
- International moves and demographic data show the UK government favours education and counselling, focusing on British Pakistani populations amid pressure from countries with bans like Norway and China and a 2021 Census figure of over 1.6 million people of Pakistani origin.

There is no ban on first-cousin marriage in Britain until October 2025, but the debate continues. The government's stance on the issue is being criticized as "promoting incest." Supporters of the practice say that public awareness and genetic testing should be used, rather than stricter laws to completely ban it.
