A man has denied murdering a fellow gig-goer at a Jessie J concert earlier this year.

As previously reported, 37-year-old Philip Sherriff died in April after being stabbed in the neck with a bottle at a BlackBerry event in London.

26-year-old Ashley Charles, from Leicester, was charged with the murder and the trial has started at the Old Bailey.

The court heard that the accused apparently told a bouncer on the night that said he "wished he had not done that".

Charles is accused of stabbing Sherriff with a broken glass bottle at the bar of the Pulse nightclub in Southwark after a row broke out. He denies the murder.

The trial continues.
