The wife of London attacker Khalid Masood left him when he went to prison
Khalid Masood’s oldest daughter, now aged 24, was also reportedly convinced by her father to change her name.
The revelation follows allegations that three years ago Masood tried to convince his youngest daughter, then aged just 16, to adopt his faith and live with him in Birmingham.
The 52-year-old had recently split from his partner, Jane Harvey, following bitter rows after she refused to allow her daughter to move from Kent.
Masood had two daughters with Jane Harvey
A close friend of Ms Harvey told the Mail: “The elder daughter converted to Islam and is living in Birmingham.
“She wears a full face veil and I think had changed her name. It was her father who had helped convert her.
“He wanted the younger daughter to convert but Jane was against it and there was quite a family struggle.
“I know Jane was very upset and wanted her to stay at home and continue her studies.”

They said: “It was a very nasty time and the police spoke to Adrian on many occasions.
“I think Jane was very glad to get out of the relationship. We were all very happy for her.”
