On Friday Attorney General Lord Hermer KC said he would not be referring the sentence to the Court of Appeal under the unduly lenient sentence scheme.
Axel Rudakubana, 18, was jailed for minimum of 52 years in January, after murdering three girls at a dance class, but the sentence sparked criticism from a family involved in the attack and MPs, alongside calls for law changes.
“It was understandable that we received multiple requests to review the sentence under the unduly lenient sentence scheme, which is designed to identify and remedy gross errors made by judges.
Southport’s MP, Patrick Hurley, previously asked the Attorney General to review the killer’s sentence as “unduly lenient”, saying it is “not severe enough”.
The Southport child killer’s sentence will not be referred to the Court of Appeal, the Attorney General has said.
