His comments come in relation to a series of changes to its statute wanted by its current leader and former prime minister Giuseppe Conte.

Grillo is being stripped of his role as the populist party’s ‘guarantor’, according to changes passed at a ‘constituent assembly’ last month.

The changes will also scrap the movement’s two-term limit for its elected representatives, make it possible to change its symbol and place it firmly in the progressive camp.

A new poll of M5S members on the changes will take place from December 5-8 after comic-and-blogger-turned-politician Grillo called for a re-vote.

“Seeing the [M5S] symbol represented by these people gives me a sense of unease,” Grillo said in a video on his blog in which he drove a hearse.

“Get yourself another symbol, go ahead and do your thing.

“The Movement is dead, but it is compostable. The humus inside is not dead.”

Grillo said less than half of the M5S’s members took part in the first vote and accused Conte of acting like the Wizard of Oz to “disintegrate the movement in its identity”.

He added that he did not think the upcoming re-vote would change anything.

“You have already decided, and I have already lost,” the 76-year-old said.

“I know it.

“But I am optimistic, because this movement had an extraordinary identity.

“I have an idea that I’ll reveal to you later. But it doesn’t end here”.
