So seventeen years ago, the Prime Minister Gordon Brown said the matters were best left to local members of the community and relevant professionals. Even the admirable Ann Cryer could only hope that people she said were in denial about the problem would come to their senses.
The evidence suggests they have not.
I was thinking edcuation of the community would slowly get rid of the practise - it used to be realtivey common in even middle class victorian britain with Darwin himself being married to a first cousin but hadn't realised it had been quite long a time period as 17 years.

There is data in Bradford of a decline
Indeed, in Bradford at least, the practice is in decline. The share of new mothers from across the Born in Bradford study who were first cousins with the father of their baby fell from 39% in the late 2000s to 27% in the late 2010s.
Which is good but perhaps a tad slow as it's still 1 in 5 couples with a decade of education though hopefully it's fallen further in last decade as well.
But crucially, Prof Oddie thinks the main risk to genetic health in Bradford is not cousin marriage, but a similar issue known as endogamy, in which people marry members of their close community. In a tight-knit ethnic group, people are more likely to share common ancestors and genes - whether or not they are first cousins, he says.
Endogamy is not unique to Pakistani communities in the UK. It is an issue too in the UK's Jewish community and globally among the Amish and also French Canadians.
"It's often the case that the exact familial tie can't be traced, but the gene occurs more commonly within a certain group, and for that reason, both parents carry the affected gene," Prof Oddie says. "It's an oversimplification to say that cousin marriage is the root of all excess recessive disorders in Bradford or in Pakistani communities. Endogamy is an important feature."
It also doesn't do enough about endogamy - clearly they also need wider genetic testing avalaible to the communities in question as well.
