It comes as a ring of steel was erected around London's landmarks to strengthen defences and prevent another attack.

Elite officers, normally based in Hereford, will be on an "immediate notice to move" and be armed with special "take-down" bullets, according to the Daily Star.

They'll also reportedly be able to enter buildings using explosives or “fast-rope” from helicopters on to roofs.

MPs are also said to be getting SAS training following the atrocity in Westminster, which left three people and unarmed police officer PC Keith Palmer dead.

Escape tactics for cabinet members is set to be reviewed after footage of Prime Minister Theresa May being scrambled to her car by armed cops emerged in the moments after the attack.

A security source told the Star: “Incidents such as last Wednesday’s attack always highlight weaknesses in any security system.

“No system is perfect but it’s important that any perceived weaknesses are addressed. People need to know how to react in an emergency.”

It's also claimed MI5, which is believed to be reviewing its intelligence gathering following the Westminster attacks, will increase its recruitment drive to monitor potential lone wolf attacks.

The number of cops have almost doubled around London and throughout the country after terrorist Khalid Masood drove his car across Westminster Bridge, ploughing through crowds before stabbing a police officer.

Part of the response to the terror attack includes huge seven-tonne cars that can withstand bomb blasts and machine gun fire put onto London’s streets, with the vehicles able to plough through barriers.

The huge Jankel armoured vehicles, manufactured in Weybridge, Surrey, include a V8 turbo-diesel engine, as well as with bullet proof glass and tyres and bulletproof glass.

The heavy-duty machines, known as “The Guardians” can also punch through barricades while being fully protected with blast resistant floors.

When asked where the vehicles are deployed and what they are armed to repel, a Scotland Yard spokesman told The Sun: "We're not prepared to discuss".

Meanwhile, the number of armed police is set to be boosted by 1,500 personnel.

Authorities have vowed to ensure London is safe - and open for business - as the capital struggles to come to terms with the terror that threatened the heart of democracy.

Acting Deputy Commissioner, Mark Rowley, said: "More widely - the police service will sustain an enhanced armed and unarmed presence over the next few days.

"London, and the UK, are open for business, and we are out there in greater numbers to make sure that the public see a highly visible presence to help reassure them as they go about their daily lives."

The top anti-terror cop added: "In London the number of armed officers remains at near double strength, while in other parts of the UK there are up to a third more armed officers on duty."

He said that the current arrangements had been developed to ensure the safety of the public without being "overly intrusive".
