A Trowbridge woman caged for stabbing her lover during a drink-fuelled attack can have no complaint about her murder conviction, top judges have ruled.

Louise Jane Cox, 46, of Newtown, admitted knifing Ian Graham, 51, at his Stallard Street flat, in Trowbridge, during a drunken spat, but insisted it was a case of self-defence.

She was, however, handed a life sentence - with a minimum jail term of 14 years - at Bristol Crown Court, in May, 2013, after a jury found her guilty of murder.

Today, three of the country's most senior judges at London's Appeal Court rejected a conviction challenge by Cox. The court will give reasons for its decision at a later date.

Mr Graham suffered a 12cm-deep wound after he was stabbed with a kitchen knife on November 20, 2012.

An ambulance was called but he was pronounced dead after he being rushed to the Royal United Hospital, in Bath.

After carrying out out the fatal, drunken attack at Mr Graham's Beaufort Mansions home, Cox fled but was arrested by police at Trowbridge railway station.

Prosecutor Michael Fitton QC said today that Cox had told officers in an interview immediately after the attack: "When I stuck that knife in that bloke, I loved every minute of it. That's how you get rid of weirdos."

However, Cox's defence at trial was that she had only stabbed Mr Graham in a bid to fend off an abusive attack.

Her lawyers today argued that Cox's defence was unfairly prejudiced by the decision of trial judge, Judge Neil Ford QC, to allow the prosecution to adduce evidence of previous offences she had committed which involved a knife.

But Lord Justice Beatson, sitting with Mr Justice Holroyde and Mrs Justice Carr, concluded today's hearing by saying: "The appeal will be dismissed, we will give our reasons as soon as we can."

The judges will hand down a detailed explanation of the court's decision at an unspecified future date.
