The data reveals that as of March 31 this year, Snaresbrook Crown Court had a backlog of 4,185 cases.
This was 45 per cent higher than any other crown court, the next largest backlog in England and Wales was at Wood Green Crown Court which has 2,313 cases waiting to be heard.
The figure at Snaresbrook Crown Court was also significantly up from the year before, when there was a backlog of 3,286 cases.
Snaresbrook deals with the most serious cases from across east London.
Responding to the national figures, courts and legal services minister Sarah Sackman KC said the current rate of increase could see the backlog hit 100,000 before 2028.
This is earlier than the minister’s previous warning that it could hit the milestone by the end of 2029.
Ms Sackman said: “Despite the hard work of people across the criminal justice system the situation in our crown court is reaching breaking point.
“We inherited a courts crisis with an ever-growing backlog which, at its current rate of increase, will hit 100,000 before 2028.
“It is simply unacceptable that any victim has to wait years to see justice done and it is clear the status quo is not working.
“Only radical reform can deliver swifter justice for victims and that is why we asked Sir Brian Leveson to make recommendations for once-in-a-generation change, to be published in the coming weeks.”
The Leveson review is expected to give recommendations on how to overhaul the court system.
The government has already agreed to implement a raft of reforms following an independent sentencing review by former justice secretary David Gauke to tackle jail overcrowding.
But Mary Prior KC, chairwoman of the Criminal Bar Association, said ministers must open up closed crown court rooms to allow delayed cases to be heard, adding: “Whatever the radical reforms suggested in ongoing reviews, implementation will take at least another year.
“The traumatised people in the long queue for justice may well have walked away by then, unheard and unseen.
“Victims of serious crimes want their cases dealt with in months, not years.
“People falsely accused of crimes want the same. Both want the nightmare to end.”
In March, Justice Secretary Shabana Mahmood announced a record level of sitting days for crown court judges to tackle delays but admitted the “sad reality” is the backlog of cases will “still go up”.
The Lord Chancellor said judges will sit collectively for 110,000 days in the next financial year – 4,000 more than allocated for the previous period.
