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, who can only be identified as RXG sent encrypted messages instructing an Australian jihadist to launch attacks during a 2015 Anzac (Australia and New Zealand Army Corps) 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.

After being recruited online by Islamic State propagandist Abu Khaled al-Cambodi, over nine days RXG sent thousands of messages to 18-year-old Sevdet Besim, instructing him to kill police officers at the remembrance parade in Melbourne.

Australian police were alerted to the plot after British officers discovered material on the teenager’s phone.

The Parole Board cleared him to leave prison at his first review after he became eligible for release in October.

But the body said he will be subject to strict licence conditions, including having to live at a designated address, wearing an electronic tag and attending supervision appointments as well as adhering to restrictions on using technology and contacting people.

When he turned 18 in 2018, the boy sought an order for lifetime anonymity at the High Court, citing re-radicalisation as a reason, as well as fears his family could be at risk of attack. 

At the time, a number of media organisations made representations to the court, arguing that he should be named.

In July 2019 he was granted lifetime anonymity by judge Dame Victoria Sharp.

Dame Sharp said identifying him was likely to cause him “serious harm” and it was therefore necessary for the rare step – taken in only a small number of cases.

Only a handful of lifelong anonymity orders have been made, including those granted to Jon Venables and Robert Thompson, who murdered Liverpool toddler James Bulger, and child killer Mary Bell.
