"There is a burgeoning crisis of violence against women which as a society we need to address," Mirror quoted Trevor Phillips, commission chairman, as saying.
The report by the Commission for Equality and Human Rights was released to coincide with actress Nicole Kidman saying that a lot needs to be done internationally to end violence against women.
