A jealous jewellery designer stabbed her boyfriend to death in a champagne-fuelled rage before telling police officers "I have just killed the man I love", a court heard yesterday.

After returning from a night out with friends, mother-of-two Elizabeth Hart-Browne is alleged to have stabbed boyfriend Stephen Raynor three times with a kitchen knife whilst their children slept next door.

The altercation, which is believed to have ensued when Hart-Browne challenged her boyfriend over his supposed infidelity, resulted in Mr Raynor attempting to flee the property before collapsing in a pool of blood in front of horrified onlookers.

Appearing at the Old Bailey yesterday, Hart-Browne sat in the dock as neighbours told how they heard “hysterical” screams coming from outside, before finding the accused wailing “what have I done,” beside Mr Raynor’s motionless body.
