Looks like we might get a clown leading both sides of the parliament

Mark. Grillo's attempt was rejected, so you only have one clown to worry about here now. England already has clowns filling both positions.

 PD is in the minority in parliament- Pdl/Lega Nord are in the majority. 

Sorry, "Bill", but your point escapes me. Yes, Berlusconi and his PdL are, indeed, the majority party - that is the reason for the Berlusconi Show going on every day. Hence there being only one clown to worry about now. Obviously.

There are plenty of clowns in parliament now- Bossi and the rest of the Lega Nord deputati and senatori for starters.
