Ahead of the trial, he admitted causing death by dangerous driving and causing serious injury by dangerous driving.
Meanwhile, Mr Jhangur’s father, Mohammed Jhangur, 56, is accused of perverting the course of justice by allegedly hiding the knife used to stab Hasan Khan.
He denies the charge.
The court heard previously that a fight had erupted between two families at the wedding of Amaani Jhangur and Hasan Khan on the morning of 27 December.
CCTV footage played in court on Monday showed Mr Jhangur leaving home and driving a Seat Ibiza to College Close in Burngreave where his sister’s wedding festivities were taking place.
The compilation showed how Riasat Khan was struck by the vehicle before it disappeared out of sight and collided with a group of people further down the street.
Mr Jhangur’s mother Ambreen and his sister Nafeesa suffered life-threatening injuries, while Alison Norris and Riasat Khan suffered injuries to their heads and legs.
Father-of-two Mr Marriott was pronounced dead at the scene.
Mr Marriott and Ms Norris, a midwife, had both been on a walk with their families and had stopped to help Nafeesa Jhangur who they saw collapsed in the road.
During Monday’s hearing, the jury was also played a 999 call made by Ambreen Jhangur just as the collision took place.
In the audio clip, she can be heard requesting an ambulance for her daughter, who she said was lying unresponsive in the road before the call is interrupted by screaming and shrieks.
Another call, which had been made simultaneously by Riasat Khan, recorded an “escalation in the level of screaming”, the prosecution said, with some people heard shouting “they’ve got knives”.
