In the last twenty years the PD has been in government for at least 10 years and in the last 18 months it has been in the super-government with the PDL voting for any rubbish from Rigor Montis. Hand shakes and daily hugs between Alfano and Bersani in the Lower House, do you remember?
The M5S will not support any “confidence vote” for the PD (nor for the others). In parliament it will vote for the laws that are in accordance with its programme irrespective of who proposes them.
