First cousin marriages, though legal in Britain, are a taboo - commonly seen as incest.
Food for thought:
"The practice is most common in Britain's Pakistani community, in which more than 50% of people marry their first cousin, and in Bradford 75% of ethnic Pakistanis follow the tradition."... but the real Xenophobics are of course the freedomloving patriots, right?
Dispatches reveals the tragic consequences of these relationships.
First cousin marriages cause hundreds of children to be born with terrible disabilities in Britain every year; one third of whom are so ill that they die before they are five years old.
The practice is most common in Britain's Pakistani community, in which more than 50% of people marry their first cousin, and in Bradford 75% of ethnic Pakistanis follow the tradition. It is also common in some Middle Eastern and East African communities here, and in the UK's Bangladeshi community, nearly a quarter of people marry their first cousins.
But the practice isn't uncommon in the white British community either: this documentary features a couple, first-cousins-once-removed, whose daughter died of a genetic disease.
The medical risks include infant mortality, birth defects, learning difficulties, blindness, hearing impairment and metabolic disorders. As adults, the offspring of these relationships also risk sporadic abortions or infertility.
Reporter Tazeen Ahmad meets affected families, including one with three children with serious degenerative genetic diseases. Tazeen's own grandparents were first cousins: five of their children died before the age of ten, and three of her uncles were deaf.
Dispatches questions why no major national publicity campaign warns of these health risks. At-risk couples in some areas are offered genetic counselling, with some being offered selection of embryos or terminations, but as only 40% of recessive disorders can be medically tested for, this is of limited use.
Even talking about the practice is controversial. And, although many British studies have established the risks, people still deny the dangers and extol the benefits of marrying within the family. But others within the community say the risks should be publicised.
