The disturbance disrupted the Prime Minister mid-flow.

The man has been labelled a “legend” on Twitter.

May was forced to repeat her lines as the man ran around to the front row to stage his protest - before handing her a huge P45.

She was being applauded as she began to talk about Jeremy Corbyn’s past and present politics.

The protester headed straight for Boris Johnson, who was sat in the front few rows, before shouting angrily at him.

May was forced to come to an abrupt stop as Tory fans jeered and shouted for security to remove him.

The crowd began shouting “out, out!”

But Twitter went wild for the campaigner, labelling him  a “hero.”

Apparently completely undeterred by security forcing him out of the door the man turned and shouted back at the angry Tories.

“Shall we, er...” a clearly flustered May began.

But the room stood and cheered for her, meaning the PM was unable to begin again.

“I was about to talk about somebody I’d like to give a p45 to,” she began.

“And that’s Jeremy Corbyn.”
