Judges have ruled criminals can be jailed for their entire lives in a landmark ruling.
The decision by five Court of Appeal judges came after the European court of human rights last year said locking up prisoners for life without review was a breach of human rights.
But Lord Chief Justice Lord Thomas said the judges did not agree with the judgment because "there are crimes that are so heinous that just punishment may require imprisonment for life."
Lord Thomas added it was for Parliament "to set the framework under which the judge decides in an individual case whether a whole life order is the just punishment."
The ruling means "life means life" and was welcomed by Attorney General Dominic Grieve:
The UK judges' announcement came after convict Lee Newell appealed his life sentence for killing convincted child-killer Subhan Anwar.
Newell thought his sentence should be reduced, which would have set a precedent for future appeals. But Lord Thomas said: "This was a murder where the seriousness of the offence was exceptionally high. The judge was right in making a whole life order. This appeal is accordingly dismissed."
The ruling also increased the 40-year sentence on Ian McLoughlin, who murdered Graham Buck, to a whole life prison term and may be invoked when Lee Rigby's killers Michael Adebolajo and Michael Adebowale are sentenced.
There are currently 52 offenders serving whole life sentences, which are unsurprisingly some of Britain's most notorious criminals.
