A little in-breeding problem in England?    
Here’s an excerpt or read THE WHOLE ENCHIRITO

It is estimated that more than 55 per cent of British Pakistanis are married to first cousins, resulting in an increasing rate of genetic defects and high rates of infant mortality. The likelihood of unrelated couples having the same variant genes that cause recessive disorders are estimated to be 100-1. Between first cousins, the odds increase to as much as one in eight.
In Bradford, more than three quarters of all Pakistani marriages are believed to be between first cousins. The city’s Royal Infirmary Hospital has identified more than 140 different recessive disorders among local children, compared with the usual 20-30.
