A woman found guilty of the murder of Bradford father-of-two Andrew Ayres is appealing against her conviction.

Laura Mitchell, 22, of Bottomley Street, Buttershaw, Bradford, was jailed for life last month and told by a judge she would serve a minimum of 13 and a half years before being considered for parole.

Mitchell is also appealing against the length of her sentence.

Her boyfriend Michael Hall, 24, Henry Ballantyne, 20, and 21-year-old Carl Holmes, who were given similar jail terms, have also lodged appeals against sentence.

Mr Ayres, 50, of Queensbury, known as Ted, died after he was subjected to what the Recorder of Bradford, Judge Stephen Gullick, described as a "brutal, intense and vicious attack" in January this year.

The attack took place in the car park of the King's Head pub, in Halifax Road, Buttershaw, following a row over a taxi.

The death of Mr Ayres, who had been out celebrating a friend's birthday, was caused by Holmes, of Bonwick Mall, Buttershaw, stamping on his face at least three times as he lay helpless on the ground. Holmes pleaded guilty to murder.

Mitchell, Hall, of Bottomley Street, Buttershaw, and Ballantyne, of Spencer Road, Lidget Green, were convicted of murder and violent disorder. They were sentenced on the basis that they were secondary parties to the death.

A spokesman for the Court of Appeal in London confirmed all four had lodged appeals against sentence and Mitchell against conviction but could not say on what grounds the appeals were based. No date has yet been set for a hearing.

Hall's solicitor, Maz Khan, of Chambers Solicitors in Bradford, confirmed: "We are in the process of pursuing an appeal against sentence but I am not able to expand on the grounds for that at this stage. The process normally takes around three months to reach court."

Hall, who is being held in Doncaster Prison, told the jury during the trial that he had only pulled Mr Ayres off his girlfriend and denied intending to cause serious harm to anyone during the "stupid" fight over a taxi.

Mitchell said she had not been present when weapons were handed out. Ballantyne claimed he had no physical contact with Mr Ayres.

The trial was told how Mr Ayres was stamped on, punched and hit with a mace as he lay defenceless.

Brothers Craig and Dean Powell were also attacked.

A mace, knuckleduster and CS spray were all used during the violence, which the judge described as "wholly unjustified and unprovoked".
