Knife attacker Axel Rudakubana has pleaded guilty to murdering three young girls at a Taylor Swift-themed dance class in Southport.
The 18-year-old stabbed Alice da Silva Aguiar, nine, Bebe King, six, and seven-year-old Elsie Dot Stancombe, along with 10 others on 29 July last year, in a "meticulously planned rampage".
As his trial was set to begin at Liverpool Crown Court, Rudakubana, who prosecutors said had "shown no remorse", unexpectedly entered guilty pleas to all charges, including murder, attempted murder and terror-related offences.
The victims' families were not in court and the judge apologised to them, saying "we had all assumed" the trial would get under way in earnest on Tuesday.
Before a jury could be sworn in, Stan Reisz KC, defending, asked for the charges to be put to his client again and he pleaded guilty to three counts of murder and 10 of attempted murder, along with two terror-related charges.

Rudakubana, of Banks, a village in west Lancashire, also admitted producing the biological toxin ricin and a charge under the Terrorism Act related to possessing an al-Qaeda training manual.
Merseyside Police said the stabbing attack had not been declared a terrorist incident despite the discovery of the document.
Government sources have told the BBC that Rudakubana was referred to the government's counter-terrorism Prevent programme several times before the attack over his general obsession with violence and he had been visited by police.
The Home Secretary Yvette Cooper has announced a public inquiry will be held into the attacks.
