Britain’s youngest terrorist – who plotted to murder police officers in Australia on Anzac Day – can be freed from jail, the Parole Board has ruled.

The 20-year-old, from Blackburn, Lancashire, who can only be identified as RXG, sent encrypted messages instructing an Australian jihadist to launch attacks during a 2015 parade.

He was jailed for life in October 2015 after admitting inciting terrorism overseas.

In a document detailing the decision, the Parole Board said: “After considering the circumstances of his offending, the progress made while in detention, and the evidence presented at the hearings, the panel was satisfied that RXG was suitable for release.”

At the age of just 14, the teenager took on the role of “organiser and adviser” and suggested beheading or using a car to kill officers during the annual April 25 commemoration of Australians and New Zealanders killed in conflict, which that year marked the centenary of the First World War battle in Gallipoli.
