Hashem Abedi, the brother of the Manchester Arena bomber, will be given a life sentence when he returns to court after his conviction today for the murders of 22 people.
The case has been adjourned so that victims' families can plan to attend the Old Bailey, should they wish to.
Mr Justice Jeremy Baker said victim impact statements would also be collected
Detective Chief Superintendent Simon Barraclough of Greater Manchester Police said Abedi had shown "not one jot of emotion" or remorse throughout the trial.
When interviewed by police Abedi answered several questions, before his lawyer read a prepared statement on his behalf.
After that he replied "No comment."
