The NHS in England recorded 5,391 new cases of female genital mutilation (FGM) in the past year, data reveals.
Almost half involved women and girls living in London, NHS Digital found.
A third were women and girls born in Somalia, while 112 cases were UK-born nationals.
The practice is illegal in the UK and it is compulsory for family doctors, hospitals and mental health trusts to report any new cases in their patients.
FGM - intentionally altering or injuring the female external genitalia for non-medical reasons - carries a sentence of up to 14 years in jail.
