A veteran revolutionary convicted of assaulting the Conservative Party chairman is the force behind a “Day of Rage” protest accused of exploiting the Grenfell Tower catastrophe to overthrow Theresa May.

Extreme-Left militants are calling on demonstrators to “bring down the Government” and “shut down London” in a march on Parliament to coincide with the Queen’s Speech.

The ringleaders are accused of “hijacking” Grenfell Tower disaster to whip up support.

They are demanding the Prime Minister resigns while claiming the victims “were murdered by this rotten capitalist system”.
