SEVENTY-four other people have been released early from similar sentences to that of the London Bridge attacker, Usman Khan, Boris Johnson revealed.

The Prime Minister today blamed Labour for the terrorist being allowed out half-way through his full 16-year prison sentence - without being referred to the Parole Board.

And he said an urgent review of their licence conditions would now take place, following Friday's sickening attack, where the attacker was shot by police after stabbing two people to death.

Mr Johnson, who visited the scene of the attack with Home Secretary Priti Patel on Saturday, contrasted his zero-tolerance approach to terrorist prisoners to Labour leader Jeremy Corbyn’s and his shadow attorney-general Shami Chakrabarti.

She said it was “unedifying” to talk about “throwing away the keys” and said she was opposed to increasing prison places.

The PM told yesterday’s Andrew Marr Show on BBC One: “I do think there is an issue, as I have said, with automatic early release.

“I think it’s wrong for serious sexual offenders, I think it’s wrong for violent offenders, I think it’s wrong for terrorists.”

Revealing the immediate tightening of monitoring by the security services in the light of Friday’s attack, Mr Johnson said: “We’ve taken a lot of action as you can imagine in the last 48 hours. I don’t want to go into operation details.

“I’m sure people can imagine what we’re doing to ensure that 74 other individuals who’ve been let out early on the basis of this Labour change in legislation, they are being properly invigilated to make sure there is no threat.

“The reason this killer was out on the streets was because of automatic early release brought in by a leftie government.”

He revealed too that Mr Khan would have had licence conditions as part of his release from prison - such as restrictions on his mobile phone and internet access.

The London Bridge attack has sparked a furious row among politicians about who is to blame.

Boris has claimed a law change in 2008 meant that Mr Khan was not passed over to the Parole Board for assessing at the end of his sentence.

Khan was jailed in 2012 for his involvement in plans to blow up the London Stock exchange, then then Mayor Boris Johnson's homes and the US embassy.

He was released in 2018 after serving eight years.

But Jeremy Corbyn will this morning in a speech blame Tory cuts to public services - and blame Tony Blair's decision to invade Iraq.

The leftie boss also said he didn't agree with Boris that terrorists should serve every day of their prison sentences.

He will say later: "16 years ago, I warned against the invasion and occupation of Iraq.

"I said it would set off a spiral of conflict, hate, misery, desperation that will fuel the wars, the conflict, the terrorism, and the misery of future generations. It did, and we are still living with the consequences today."

Those changes meant that although four senior judges considered that Khan was dangerous, he was to be automatically released half-way through because of Labour’s 2008 law. That is why we are determined to change this & ensure dangerous terrorists serve their full sentence (16/16) — Boris Johnson (@BorisJohnson) December 1, 2019

What happened to Usman Khan and why was he allowed out last December? Mr Khan was jailed in 2012 for terror offences under an Imprisonment for Public Protection sentence (IPP) which allowed him to be held indefinitely until the Parole Board decided he was no longer a threat to the public.

Under the Coalition Government, those such systems were replaced with extended sentences - which carry a minimum term and ensure those cases are reviewed.

Mr Khan then successfully appealed his IPP sentence and was given a different sentence called an Extended Sentence for Public Protection (EPPs) in 2013.

That was for 16 years - of which he served eight and was released in December 2018.

But the Parole Board said they did not review Mr Khan's case at the end of his prison sentence, and were not involved.

The PM claims that Labour changed the law in 2008 which removed the requirement of Parole Board approval in EPPs, and instead it would be automatic after half the sentence.

"Had Labour not changed the law in 2008 Khan would not have been automatically released in December 2018," the PM tweeted earlier.

"Although four senior judges considered that Khan was dangerous, he was to be automatically released half-way through because of Labour’s 2008 law. That is why we are determined to change this & ensure dangerous terrorists serve their full sentence."

Boris promised last night to make sure that anyone convicted of terrorism serves all of their sentence - or at least 14 years.

Today it was revealed that the London Bridge terrorist was banned from entering London as part of his licence, but was given a one-day exemption to attend the ex-convict event where he began the rampage.

Khan fatally stabbed Jack Merritt, a 25-year-old course coordinator, and a woman, before heroic members of the public wrested him to the ground and armed cops shot him dead.

It also emerged that Khan was a student of hate preacher Anjem Choudary before he was locked up for his bomb plot.

Last night ISIS announced it was responsible for the attack, but British security sources shed doubt on the claims.

Boris also insisted there would be no tariffs or checks on goods going from Northern Ireland to Britain - contrary to what the Brexit Secretary has said in the past.

Mr Johnson said: "There will be no tariffs and there will be no checks, and what we will ensure is that the whole of the UK - Northern Ireland and the rest of us - can come out."

He was also blasted over his lack of plans for social care.

Boris admitted: "I accept that the full plan needs to be developed."
