The brother of the Manchester Arena bomber is due to be sentenced in August - five months after he was convicted.
But the victims' families will likely be denied the chance to see Hashem Abedi receiving his jail sentence, as it is expected that he will remain in his prison cell and won't attend.
He will be jailed for life, with a minimum term to be imposed.
He helped his suicide bomber brother Salman prepare for the attack.
The wait to see justice done has been a long one for the families of the victims of the devastating May 2017 attack. 22 people were killed and hundreds more were injured when Salman Abedi detonated an improvised explosive device in his backpack as concert-goers were leaving an Ariana Grande gig at Manchester Arena.
Hashem Abedi was 2,000 miles away in Libya when his brother killed himself and 22 others.
But, following a seven-week trial at the Old Bailey, a jury decided he was also guilty of the ISIS-inspired mass murder.
He had encouraged his brother and helped to build the IED by sourcing shrapnel and chemicals required to make the deadly TATP explosive.
The Manchester-born pair, of Libyan heritage, manufactured the explosive at a 12th floor apartment they rented in Blackley before their parents, back in Tripoli, became concerned something was amiss and returned to Manchester a month before the the attack to fly them back to Libya.
Salman Abedi returned alone on May 18, 2017, and collected the explosives from a car the pair had left in Rusholme before he assembled the device at an apartment in Manchester city centre.
Hashem Abedi was arrested in Tripoli two days after the Arena atrocity and held there before he was extradited back to the UK in 2019.
His trial was due get underway in November 2019 but Abedi sacked his defence team, causing the first of many delays to the case.
When the trial eventually started in January, Abedi refused to come into court for much of the latter stages of the case and he sacked his replacement defence team.
As coronavirus swept through London, one of the jurors had to be discharged because they developed symptoms but the remaining 11 members of the jury found him guilty of 22 counts of murder, one count of attempted murder concerning the hundreds who were injured but survived, and conspiring with his brother to cause an explosion.
He wasn't in the dock when he was convicted.
The trial judge, Mr Justice Jeremy Baker, had hoped to pass sentence in April and then in June or July but the lockdown thwarted these plans.
Court officials have now indicated that he will sentenced following a two-day hearing in the week beginning August 17.
The judge had written to Abedi to tell him officially he has been convicted and to ask whether he will either attend the sentencing hearing or make any submissions.
The defendant has indicated he will do neither.
Convicted of 22 counts of murder, the only question is what the minimum term will be before he can be considered for parole or whether he will be given a whole life tariff, which would mean he is unlikely to ever be released from prison.
After the jury convicted Hashem Abedi, detectives described him as a ‘proper jihadi’ who may have been plotting further terror attacks.
The eventual sentencing hearing, like the trial, is expected to be beamed via video-link to courts in Manchester, Leeds, Newcastle and Glasgow so families affected by the attack who cannot attend the Old Bailey can watch the proceedings.
