Hurley joined Conservative leader Kemi Badenoch in calling for law change to allow for whole life orders to be imposed on people aged under 18 in some cases.
Badenoch said “Rudakubana should never be released from prison” after destroying “countless lives” and sowing a “legacy of mistrust” across the country.
The Conservatives “will start to explore” how to change the law, she said.
Despite the severity of the attack the Crown Prosecution Service (CPS) decided it did meet the legal definition of terrorism, due to a lack of evidence Rudakubana sought to advance any political, religious, or ideological agenda.
But Badenoch called the attack a “terrorist” incident, and called on others to stop “avoiding these hard truths”.
Leader of Reform UK Nigel Farage demanded the CPS chief resign for failing to class the case as terrorism.
“This barbaric and senseless attack was clearly both political and ideological,” Farage said.
“The British public needs to have confidence in the CPS and our police forces. Tens of millions of British citizens will find it incomprehensible how the CPS decided this was a non-terror incident and maintained that position.”
