Labour MP Jo Cox died from multiple stab and gunshot wounds, a coroner has been told.

An inquest into the death of Mrs Cox has been opened and adjourned today, after she was attacked outside her constituency surgery in Birstall, West Yorkshire, just over a week ago.

Detective Superintendent Nick Wallen, of West Yorkshire Police, told a brief hearing at Bradford Coroners Court it was immediately clear to paramedics and police that the 41-year-old mother of two young children was “very seriously injured indeed.”

Mr Wallen said medics worked to save her life but she was pronounced dead by a doctor in an ambulance outside Birstall library on June 16.

She did not go to hospital.

The detective confirmed that a post-mortem examination had shown a preliminary cause of death as “multiple stab and gunshot wounds.”

He said lawyers for Thomas Mair, the man charged with murdering the Batley and Spen MP, did not require a second post-mortem examination.

Coroner Martin Fleming said this meant he could release Mrs Cox’s body “so the family can get on with the grieving process”.

Mr Fleming adjourned the six-minute inquest hearing until the conclusion of criminal proceedings.

None of Mrs Cox’s family were in court for the hearing.

Mr Wallen gave brief details about what happened in Birstall, saying the first injured person spotted by police and paramedics was Bernard Kenny – the pensioner who was stabbed as he came to Mrs Cox’s aid.

The officer told the court: “On Thursday June 16, 2016, at just after 12.52pm, both the police and ambulance service were called by a number of emergency calls to Market Street in Birstall town centre where initial information was that a man armed with a gun and knife had attacked and seriously injured a man and a woman."

“Police officers and paramedics arrived quickly at the scene and firstly found a male named Bernard Carter Kenny, aged 77, being tended to by members of the public.

“He had sustained a stab wound to the abdomen.”

Mr Wallen said the emergency services also found a woman being tended to by members of the public “who, it was immediately clear, was very seriously injured indeed.”

He said: “A number of people informed the police that the lady was Jo Cox, member of parliament for Batley and Spen.”

The detective said Mrs Cox was taken into an ambulance by paramedics and emergency doctors who “tended to her but were unable to save her life.”

He said she was pronounced dead at 1.48pm.

The coroner was told that Mrs Cox was formally identified by her sister, Kim Leadbeater, at a mortuary in Bradford.

Mr Wallen confirmed that Mair has been charged with murder and other offences and is due to appear at the Old Bailey again later this year.

Opening proceedings, the coroner said Mrs Cox’s death was “very sad”. He referred to her full name – Helen Joanne Cox.
