A jealous Ealing woman stabbed her boyfriend to death in a champagne-fuelled rage before later declaring to police "I have just killed the man I love", a court has heard.
Jeweller Elizabeth Hart-Browne is on trial at the Old Bailey charged with the murder of Stephen Rayner, 25, at their Hanwell flat on September 17 last year.
Prosecutor Rosina Cottage QC said a row erupted after the mother-of-two arrived home from a family party where she had been drinking.
Children were sleeping just feet away
Hart-Browne, of Baker House in Nightingale Avenue, allegedly picked up a large kitchen knife and stabbed Mr Rayner three times, inflicting a fatal wound to the neck while young children slept just feet away
The prosecution said the couple had been in a "volatile" relationship for six years and said it was "on-off" and involved both physical and verbal aggression on both sides.
'Jealousy and controlling behaviour'
Ms Cottage said: "The rows appear to have been stimulated by allegations of infidelity against Stephen Rayner and jealousy and controlling behaviour by the defendant.
"In the days leading up to the events of September 17, the defendant and Stephen Rayner had been arguing about his behaviour and her jealousy."
The 27-year-old had been at a party and came home by tube to find her boyfriend already in bed, the court heard.
Heard shouting and crying
A loud argument broke out and she was heard shouting and crying, jurors were told.
A neighbour allegedly heard a woman screaming: "He's dead, he's been stabbed."
She ran outside and found Hart-Browne leaning over her boyfriend laying in a pool of blood.
'I didn't mean to do it'
She allegedly told a police officer she stabbed him, saying: "I didn't mean to do it, I'm so sorry."
The court heard Hart-Browne was distressed on being told Mr Rayner was dead and told police "I have just killed the man I love".
In interview, she said she had drunk champagne and wine that night but denied being drunk.
On arriving home, she said she got into bed fully clothed but became upset at Mr Rayner again.
Defendant said she hit him with the knife accidentally
She got up to have a cigarette and Mr Rayner began hitting her and holding her by the throat, she said.
Hart-Browne said she waved a knife at him and pushed her partner as he held on to her neck and hair.
According to her account, she hit him with the knife unintentionally.
She saw the blood and Mr Rayner held his neck, allegedly telling her: "You're mad you are" and walked out.
Hart-Browne, who sat in the dock wearing blue jeans and a pale blue sweater with her long blonde hair in a ponytail, denies murder.
Used the knife to defend herself, she says
Ms Cottage said: "The defendant says that she picked up a knife from the living room table to defend herself while she was being violently attacked and that during the struggle they stumbled and Stephen Rayner was accidentally injured.
"The prosecution say that she is lying and that she deliberately armed herself with a knife from the kitchen and just as deliberately stabbed Stephen Rayner with it intending at least to cause him serious harm, if not to kill him."
Toxicology tests showed the defendant was twice the legal drink drive limit and the prosecutor told jurors the alcohol "may well have influenced her temper and decision-making".
In an opening address for the defence, James Scobie QC told jurors the relationship between his client and Mr Rayner was both "golden" and "grim".
He said: "She was emotionally dependent on the man she loved and the man she killed."
The trial continues.
