As reported by the BBC, the 54-year-old admitted dangerous driving, affray, 17 charges of attempting to cause grievous bodily harm (GBH) with intent, nine counts of causing GBH with intent and three counts of wounding with intent at Liverpool Crown Court.
The Daily Record report that Doyle was tearful as he re-entered his pleas, sitting with his head in his hands and sobbing repeatedly as the charges were read to him.
More than 100 pedestrians, ranging from children aged as young as six months to a 78-year-old woman, were injured the incident which caused the city to stand still amid the title celebrations.
Sarah Hammond, chief crown prosecutor for the Crime Prosecution Service, said Doyle had come to terms with what he had done.
"Dashcam footage from Doyle's vehicle shows that as he approached Dale Street and Water Street, he became increasingly agitated by the crowds," she said.
"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.
"I would like to commend the bravery of emergency services who acted swiftly at the scene. There can be no doubt that their actions saved lives. Liverpool as a city has shown resilience and unity in the face of this awful act, and I hope the victims, their families and anyone affected will feel justice has been done."
