As a father Iftacan said along with the challenging moments there is a lot of joy.The possibility of genetic illnesses did cross his mind but that many of his close relatives who had married their cousins had never had any problems to cause him any concern.

And for British Pakistanis the practise is common with an estimated 55 percent of them doing so.

For some Muslim girls it is an arrangement they agree to in order to keep their families happy, as Bradford-born Hiba Maroof discovered in BBC Three documentary 'Should I Marry My Cousin'.

Britain's first Asian peer Baroness Shreela Flather has made calls in the past for British Pakistani communities to ensure cousins have DNA tests before getting married.

A former barrister who sits in the House of Lords, she shared her own thoughts on the topic in 2015.'There are a lot of first-cousin marriages in certain communities, particularly among Pakistanis who come from the Pakistani Kashmir area.

A recent report revealed that while British Pakistanis were responsible for three per cent of all births, they accounted for 30 per cent of British children born with a genetic illness.

'That many children shouldn’t be disabled if it can be helped.'I’m not going to lie the genetic talk scares me,' Hiba said.While one sister is happy to get married to her first cousin whom she has known since childhood and has been engaged to for a year, the second sister is entering an arranged marriage.'I don’t know much about my future husband,' she confesses to Hiba moments before her wedding ceremony. I’m seeing him today for the first time since our marriage was fixed a year ago.'Hiba is an inquisitive teen who is keen to get married but wants to find a 'good-looking' man who is 'trustworthy and open-minded'.Divorcee Sabbah, 21, explained that her marriage breakdown was because she didn't have the backing of her family to help her.'In family if something goes wrong in the marriage you can at least ask them because they are family, they look after you properly.'As for me I got married outside [my family] and it was really hard.' She explained that if she had another opportunity to get married the second time round would be completely different.'I would marry inside the family, it would be so much better.' Although security and stability are a plus for Hiba in cousin marriages - which one Imam Mohammad Sayed, says has become a more 'cultural thing than religious' - the medical issues still bothers the teenager.'I think after meeting all the people and all the places I have been, I decided not to marry my cousin, it wouldn’t be something I would be comfortable with.'The advantages don’t weigh up for me.
