A BROTHER of Scissor Sisters Linda and Charlotte Mulhall has pleaded guilty to repeatedly stabbing his girlfriend.
James Mulhall (40) could now face life in prison if he is given the maximum penalty for grievous bodily harm.
Margaret McNamee suffered more than a dozen stab wounds in the life-threatening attack in late September while her four children were in their UK home.
Her family had to travel from Tallaght to take care of the children after the savage assault.
Mulhall is originally from Tallaght but has been living in England for a year.
He was brought before Leeds Crown Court yesterday where he pleaded guilty to wounding and causing grievous bodily harm with intent.
He was remanded in custody for sentencing on November 2.
He is the eldest brother of Linda (35) and Charlotte (29) Mulhall, currently in jail for killing their mother's partner Farah Swaleh Noor.
He is not long out of prison where he served a sentence for robbing two prostitutes in their Dublin homes.
Mulhall and an accomplice took €800 in cash and nine mobile phones from one of the women at Isoldes Towers apartments in Dublin city, and €250 in cash, an iPod and five mobile phones from their second victim at The George, Charlotte Quay, Ringsend.
He forced his way into the flats after telling the women he was a garda.
Mulhall, who was living in Ardmore Walk in Tallaght at the time of the attacks in 2006, told gardai he did it because he was desperate for money to support his own six children along with his sister Linda's four children, who he took on after she was sentenced to 15 years for manslaughter.
Charlotte is serving life for Noor's murder.
Noor was killed at a house at Richmond Cottages, Ballybough in 2005.
His body was chopped up by the two sisters and dumped in the Royal Canal while his head was brough to Tallaght and hidden in a park.
It has never been found.
Charlotte and Linda's mother Kathleen was jailed for five years in 2009 after admitting helping cleaning up the crime scene to help her daughters.
The Mulhalls' father John took his own life after his two daughters were charged with the killing in 2005.
