League leader Matteo Salvini has called for an end to insults after his coalition partner, ex-premier and Forza Italia leader Silvio Berlusconi, compared the anti-establishment 5-Star Movement to Nazis.
Berlusconi said that many people felt like "jews when Hitler appeared" with respect to the M5S.
The M5S refused to negotiate on forming a new government with the centre right after last month's inconclusive general election as Salvini rejected their call for him to dump Berlusconi to make a deal possible.
"It's better to be silent and respect the vote of the Italian people instead of talking nonsense," said Salvini. "I want to give Italy a government. I'm fed up of insults, tantrums and quarrels".
