This is the convicted terrorist who will be back on British streets unless MPs can win a frantic race to rush through emergency terror laws by February 27.

Mohammed Zahir Khan, from Sunderland, is the next offender due for automatic early release on February 28 following a four and a half year sentence.

Ministers face a deadline of February 27 to pass the emergency legislation through Parliament that would end automatic release for offenders after half their sentence.

The prime minister announced the legislation following an attack in Streatham on Sunday, in which convicted terrorist Sudesh Amman, who was released last month despite authorities having serious concerns about him, went on a stabbing spree.

Khan, a father-of-one and shopkeeper, was jailed in May 2018 for encouraging acts of terror, disseminating terror material and inciting religious hatred.

A Whitehall official described him as an 'extremely concerning individual'.

MPs are hoping the legislation will pass through the Commons by the end of next week, before Parliament breaks for a week's recess.

That means the House of Lords will have just three days to pass the bill when Parliament returns on February 24.

Khan 42, originally from Birmingham, was locked up after he admitted possessing a dossier of terror material.

He said initially that had amassed the bile filed material 'recklessly' but a Judge called him out for his 'uninhibited hatred.'

Khan spread racial hatred online targeting Shia Muslims saying 'death to shias ... death to every single one of them', describing them as 'dirty and filthy shiite scum' and calling for them to be burnt alive.

He also tweeted in January 2017: 'Welcome to the year of fear, IS will make this one the deadliest ever. Mr Kuffar (non-believers) prepare for real war.'

His Facebook page also showed an Islamic State flag and a statement about martyrdom.

Judge Paul Sloan QC told him: 'You had an uninhibited hatred for Shiite Muslims, President Assad and his regime, non-believers and hatred for some Western countries such as the US.'

They are among 50 terrorists who are due for early release this year.
