BRITAIN'S youngest terrorist, a boy from Blackburn known only as RXG, is due to be let out of prison this month as the government attempts to rush through a law halting automatic release for terror convicts.

The teenager received a life sentence with a minimum term of five years in 2015 for plotting to murder police officers in Australia.

Reports suggest that Atiq Ahmed, from Oldham, who was found to have IS propaganda on his phone, is due to be released in March.

Bolton chemistry teacher Jamshed Javeed, who was jailed for six years in March 2015 for planning to travel to Syria to join terror group Islamic State, is also expected to be let out next month.

A target of February 27 has been set to rush the Bill through Parliament in order to prevent the automatic release of any further terrorists.

Currently, prisoners are considered for early release halfway through their sentence by a panel of specialist judges and psychiatrists at the Parole Board.

After the Streatham terror attack last week, police chiefs warned the threat of terrorism was “not diminishing”.

A Whitehall official said: “If the legislation is passed by February 27, we can prevent the automatic release of any further terrorist suspects who might pose a threat to the public.”

Convicted terrorist Sudesh Amman wore a fake suicide belt as he grabbed a knife from a shop in Streatham High Road, south London, on Sunday, before stabbing two bystanders.

The 20-year-old had been jailed for possessing and distributing terrorist documents in December 2018 but was freed automatically halfway through his sentence less than two weeks ago.

It is understood that another offender is due for release on February 28, with around five expected to be let out in March unless the new law is in force.

There are 224 terrorists in prison in Britain, and up to 50 could be freed from jail this year, figures suggest.

The UK's terror threat level is currently at "substantial", meaning an attack is likely. It was downgraded from "severe" in November, shortly before the London Bridge attack.

Metropolitan Police assistant commissioner Neil Basu, head of UK counter-terror policing, has welcomed the plans to halt automatic release.

He said: “Police and the security services knew the attacker posed a significant risk and we were, unfortunately, proved right in our decision to place him under surveillance.

“But with 3,000 or so subjects of interest currently on our radar, and many convicted terrorists soon due to be released from prison, we simply cannot watch all of them, all the time.”

Justice Secretary Robert Buckland said the urgent legislation was needed to ensure offenders serve two-thirds of their sentence before they are considered for release.

The Government plans to introduce the legislation in the Commons on Tuesday next week, with the aim of clearing the House by the time it rises for recess on Thursday.

The Bill will then go to the Lords on February 25 with the aim of getting royal assent on February 27.
