PARLIAMENT was hit by a major security breach this afternoon after an intruder slipped past police before being dramatically chased down.
Armed cops wrestled the suspect to the ground and trained their guns on him as more officers swooped in.
The unknown man was arrested on suspicion of trespassing on a protected site.
The main gates to Parliament – where Boris Johnson and senior Ministers gathered just this morning – was plunged rapidly into lockdown.
At around 3.30pm the suspect was bundled into a Met Police van and whisked off the Parliamentary Estate.
Dramatic photos show a bike strewn on the floor a good distance from where the man, wearing jeans and a coat, was being pinned.

It appears the intruder snuck in near the Carriage Gates entrance by Parliament Square which MPs and Lords usually use.
It’s yards from the spot where in 2017 PC Keith Palmer was stabbed to death in a terrorist attack.
A Scotland Yard spokesman said: “At around 15:00hrs on Wednesday, 1 December, a man was detained and arrested at Carriage Gates inside the Palace of Westminster on suspicion of trespassing on a protected site.
“Enquiries into the circumstances continue.”
Hundreds of armed cops and security staff are deployed to Parliament every day making it one of the most guarded buildings in Britain.
There was a heightened police protest today because of the usual protests that amass outside the Commons on a Wednesday for PMQs.
