The internal conflict within Italy's Five Star Movement (M5S) is intensifying as Giuseppe Conte and Beppe Grillo prepare for a decisive showdown.

The party recently launched a campaign to update its membership list, which could significantly reduce the number of registered members.

This move is crucial as it affects the quorum needed for upcoming votes, including the Constituent Assembly in October.

Grillo, the party's founder, has raised concerns about the transparency and fairness of this process, questioning the methods used to verify memberships.

He has also sought clarity on who has access to the party's database.

As tensions rise, both leaders are gearing up for potential legal battles, with Grillo considering challenging the leadership and statutory votes.

The outcome of this internal struggle could reshape the future of M5S.
