Paul Doyle has pleaded guilty to causing the Liverpool parade crash.
The 54-year-old from Croxteth initially denied all 31 charges after more than 130 people were injured when a Ford Galaxy drove into a crowd on Water Street in May.
He also entered not guilty pleas to four amended counts of causing GBH with intent, wounding with intent and attempting to cause GBH with intent over the incident.
But Doyle stunned Liverpool Crown Court on Wednesday (November 26) as his counsel Simon Csoka KC asked for his client to be rearraigned on all charges.
Appearing in the dock wearing a black suit, glasses and slicked back hair, he admitted to all counts just a day after a jury had been sworn in for a four-week trial.
Judge Andrew Menary KC, Honorary Recorder of Liverpool, informed Doyle that he will be sentenced over December 15 and 16 and should expect a prison sentence.
Sarah Hammond, chief crown prosecutor for the Crown Prosecution Service in Mersey-Cheshire, said: “By entering guilty pleas, Doyle has finally accepted that he intentionally drove into crowds of innocent people during Liverpool FC’s victory parade.
“Dashcam footage from Doyle’s vehicle shows that as he approached Dale Street and Water Street, he became increasingly agitated by the crowds.
“Rather than wait for them to pass, he deliberately drove at them, forcing his way through.
“Driving a vehicle into a crowd is an act of calculated violence. This was not a momentary lapse by Paul Doyle — it was a choice he made that day and it turned celebration into mayhem.”
