A man has pleaded guilty to causing the deaths of brothers Corey and Casper Platt-May by dangerous driving in Coventry.
Robert Brown, aged 53, crashed into the boys, aged six and two, as they walked to the park with their family.
He will be sentenced on April 27 at the same court after Tyrone Smith QC, defending, said the presiding judge would need to watch "troubling" CCTV footage before passing sentence.
Judge Anthony Potter told Brown: "I'm satisfied there's good reason for adjournment in your case. In the meantime, you will be remanded into custody."
Brown remained calm in the dock at Warwick Crown Court today, having shouted "this is a f****** kangaroo court" at an earlier magistrates' court appearance.
He was emotionless as he admitted all charges – including two counts of death by dangerous driving, driving whilst disqualified, using a motor vehicle without insurance and using a motor vehicle without a licence.
Brown's co-accused Gwendoline Harrison, 42, denied charges of perverting the course of justice and common assault at the same hearing today.
Corey and Caspar's mother Louise Platt-May, who was with her sons at the time of the tragedy, paid tribute to the boys after their deaths.
She said Corey was an "amazing boy" who had a passion for football, while younger son Caspar was a "cheeky little boy" whose "smile could light up any room".
The two boys were taken to hospital with severe injuries after being struck down by Brown's black Ford Focus.
Casper died a short time later, while Corey was rushed into surgery but also later died.
Their mother was unhurt.
The boys' aunt Chelsea Platt-May also witnessed the crash in the Stoke area of the city at roughly 2pm on Thursday, February 22.
She told Sky News: "We were all in a row crossing the road, doing our usual checks, double checks, we were all bubbling to go to the park.
"It wasn't until we were about half-way that we noticed that there was a car right next to Corey, and then there was a sound of crushing plastic and the screeching of tyres.
"In that moment of hearing crushing plastic we all froze and it wasn't until we heard a scream that we knew something was wrong.
