NHS Guidance on First-Cousin Marriage Prompts Renewed Calls for Ban

The guidance cites a 4–6% risk for children of first cousins, recommending genetic counselling over a ban.

Overview

  • NHS England’s Genomics Education Programme published educational material acknowledging a modestly higher genetic risk for children of first cousins and advising public-health measures rather than criminalisation.
  • Critics including Conservative MP Richard Holden condemned the stance as politically motivated and urged legislation to outlaw first-cousin marriage.
  • Reports note a Bill to prohibit such marriages is currently before Parliament, with its supporters arguing a ban is necessary on health, integration and women’s rights grounds.
  • A YouGov poll reported this year found 77% of Britons think first-cousin marriage should not be legal, indicating broad public backing for a ban.
  • Coverage cites data highlighting higher local prevalence in some British Pakistani communities, including Born in Bradford findings and city figures linking a notable share of congenital cases to Pakistani heritage, with some critics alleging significant NHS costs.
