Sania Bibi, 20, was allegedly forced to work 17-hour days as she cooked, cleaned and washed clothes for her husband Haroon Akhtar's family.
She was usually attacked at least twice a day by her husband, who threw her down the stairs on one occasion after his mother complained she had not been doing her chores properly, the jury heard.
Within days of his wife's arrival in the UK Akhtar, 28, is said to have told her that he planned to remarry and would force her to look after his new bride's children.'He said, "You are not good enough for me" and he would get married a second time and he would have children through his second marriage and I would have to take care of these children.'
Giving evidence from behind a screen and using an interpreter, Mrs Bibi - who said she came from a middle-class family - said her gruelling days lasted from 6am to 11pm.
