The UK government’s endorsement of first-cousin marriages has stirred significant debate. Despite these unions being legal in numerous countries and faiths, the government’s National Health Service (NHS) has promoted their benefits, causing outrage. The NHS has compared the possible genetic risks to those stemming from other factors, such as delayed pregnancies or substance abuse during pregnancy. This has met with strong criticism.
First-cousin marriages have been legal in Britain since the 16th century. Current legislation forbids marriages between close relatives like parents, children, and siblings, but not between first cousins. A Conservative MP has introduced a bill aimed at banning these marriages, citing potential health risks to children. This bill is up for further discussion. An article from NHS England’s Genomics Education Programme considered a potential ban while also highlighting advantages, like strong family support systems and financial gains, despite acknowledging the increased chance of birth defects. Critics, including Bradford’s NHS, have expressed concern. Ayesha Ali-Khan, who lost three brothers to related health complications, blames her parents’ marriage and does not want others to go through her experience. Anita Prem from Freedom Charity considers these marriages a safety risk.
Research reveals that children from first-cousin marriages face a higher likelihood of inheriting recessive disorders. They also may face increased odds of encountering speech, language, and developmental challenges. Though the prevalence of these marriages decreased in the 20th century, they continue in specific communities, as evidenced in Bradford, where nearly half the women of Pakistani origin are in these types of unions.
