Our thanks to Tim for pointing us to a piece published by 15 Square, which has a link to this. From the article:
In 2013, the clinic owner, also named Dr Nadeem Ahmed, was issued a warning for performing a circumcision on an eight-year-old boy without getting consent from both parents.
Circumcision is considered compulsory by most Shi’a Muslims, and while not mandatory for Sunni Muslims, the practice is still strongly encouraged as it is seen to improve cleanliness.
It is also considered to be a sign of belonging to the Muslim community. [Note: or the Jewish community.]
However, the procedure is not without its risks, as 5% of children who underwent circumcision in Central Manchester in 2014 were subsequently admitted to A&E. [my emphasis]
