Rome, August 19 (RHC)-- One of the two political groups forming Italy's rightist government, the 5-Star Movement, has said its former ally and the leader of the far-right League, Matteo Salvini, is an unreliable interlocutor without credibility.

The comments have been made after Interior Minister Salvini tried to patch things up after terminating a 14-month 5SM-League government earlier this month and calling for snap elections that could crown him as prime minister.

The 5SM political leader Luigi Di Maio have said Salvini is now trying a "shameful U-turn" after offering him to find a new accord on the terms of their alliance.

The Italian media have reported that center-left Democratic Party and its former rivals the Five Star Movement seem inclined to put aside their differences to discuss ways to shape a new government avoiding snap elections, thwarting this way Salvini's ambitions to become prime minister.

Former Prime Minister Matteo Renzi has urged his fractious party to unite and support a caretaker anti-Salvini government.  On Monday, however, Five Star Movement minister for relations with parliament, Riccardo Fraccaro, and Justice Minister Alfonso Bonafede denied their movement would make a government deal with Renzi.

On Tuesday, Italian Prime Minister Giuseppe Conte is slated to brief the Senate over Italy's political crisis after the far-right League's leader Salvini filed a no-confidence motion in his executive.  In the upper house Conte could face a vote of no confidence or may choose directly to resign.
