Parma mayor confirms 'unauthorized' meeting, rankling Grillo
Expelled 5-Star parliamentarians forming own group04 March, 16:55
But the latest incident has brought tensions within Italy's second-biggest political force to a head amid accusations of hypocrisy on his part.
In protest last Thursday, six M5S Senators presented their resignations as parliamentarians, siding with the ousted members in arguing that Grillo had betrayed the founding principles of the movement and had taken his high-handed methods one step too far.
On Tuesday, Senator Lorenzo Battista said he and his fellow expelled M5S parliamentarians were forming their own group.
"It will be more democratic than the M5S," he said. "There won't be any leaders and everyone can express their thoughts freely".
