Hanim Goren said she was against her daughter's relationship
A father accused of murdering his daughter in a so-called "honour killing" beat her up badly, his wife has told the Old Bailey.
Mehmet Goren, 49, denies killing Tulay Goren, 15, from Woodford Green, north London, who went missing in 1999.
But his wife, appearing for the prosecution, said Mr Goren attacked his daughter when she carried on seeing a Halil Unal, who he disapproved of.
Mr Goren collapsed after an apparent seizure as Tulay's mother testified.
The judge had adjourned the trial to allow Mr Goren to recover.
The jury heard from his wife Hanim Goren about how the 15-year-old girl met Mr Unal, who was a supervisor at a factory, in 1998 while she was on a summer job there. Mrs Goren also worked at the factory.

Mr Unal then began collecting Tulay from her school.
Mrs Goren said Mr Unal had asked her permission to befriend Tulay, who was 15 years younger than him, but she disapproved of their friendship and had warned Mr Unal against befriending her daughter.
She said she was against it because of the age gap and their religious differences.
Mr Unal was a Sunni Muslim while the Gorens followed the Alevi branch of Islam and their relationship "would not have been tolerated", the court heard.
Mrs Goren said her husband confronted Mr Unal in the factory where he worked.
Speaking through an interpreter, she said: "Mehmet started saying, 'whose child would you take out from school? Whose child would you bother?'
'Beaten up badly'
"Then Mehmet grabbed him around the collar and slapped him with his hand."
Mrs Goren said members of her family caught her daughter trying to contact Mr Unal on several other occasions.
This culminated in Mr Goren "beating up" his daughter "badly", the court heard.
After that attack Tulay ran away from home and began living with Mr Unal.
Some men representing Mr Unal then visited Tulay's family and persuaded them that the two should get married.
But the marriage at Hackney Town Hall did not go ahead because, at 15, Tulay was legally too young.
Mrs Goren told the court: "Nobody sat down and asked me [if I thought Tulay should get married].
"Mehmet himself made the decision and when Mehmet said it I said yes."
Tulay's uncles, Cuma Goren, 42, of Evesham Avenue in Walthamstow, east London, and Ali Goren, 55, of Brettenham Road, Walthamstow, also deny murdering her on 7 January 1999.
Mehmet Goren and his brothers also deny a charge of conspiracy to murder Mr Unal between May 1998 and February 1999.
