Ali Harbi Ali will die in jail after being handed a whole-life prison term for the murder of Sir David Amess MP, which he claimed was a retaliation against politicians who voted to bomb Syria.
Mr Justice Sweeney handed down his sentence at the Old Bailey on Wednesday and said 26-year-old Ali "has no remorse or shame for what he has done – quite the reverse".
He added: “This is a murder that struck at the heart of democracy.”
It means he joins a handful of prisoners who will never be released from prison.
Whole-life orders, or whole-life tariffs as they were formally known, are for the most serious cases of murder and were previously imposed by Home Secretaries from 1983 until 2003.
Judges have had the power to impose whole-life orders since the Criminal Justice Act (CJA) in 2003.
Convicted criminals who are sentenced to a whole-life order must be at least 21 years of age.
There were 61 criminals serving whole-life orders, according to Government figures to the end of 2021.
Some of the most notorious criminals on the list include:
David Fuller
In December last year, Fuller was handed a whole-life tariff for the murders of Wendy Knell and Caroline Pierce in 1987 and the sexual abuse of more than 100 dead women and girls in hospital mortuaries.
Wayne Couzens
