A teenage girl who stabbed another to death in the street during a pre-planned fight over a boy has pleaded guilty to murder.

Chloe Watson Dransfield, 16, was taken by her boyfriend Blake Dowling, 18, to the home of Kayla Smith, 18, who fatally stabbed her in the early hours of March 28.

Leeds Crown Court heard that Dowling had been in “on-off” relationships with both girls, and they would regularly argue over him.

Dowling’s mother said Smith was “jealous and obsessed” over her son’s relationship with Chloe.

Smith had pleaded guilty to manslaughter but denied murder.

However, on the second day of her trial on Thursday, she pleaded guilty to the more serious charge.

The trial will continue for her two co-defendants, Dowling and Archie Rycroft, 20, who followed Smith to the fight and is accused of recording it on a phone.

Dowling and Rycroft both deny murder and manslaughter.

The judge, Mr Justice Cavanagh KC, said he would sentence Smith once the trial was over.

He warned her that the only sentence he could pass for murder was life imprisonment, but that he would need to set the minimum term she must spend in custody.

The trial continues.
