Matteo Renzi has arrived at Italy's presidential palace where he is widely expected to be asked to form a new government.

President Giorgio Napolitano summoned Renzi on Monday morning after Premier Enrico Letta was sacked by his own party in a mutiny orchestrated by Renzi.

Assuming the 39-year-old mayor of Florence gets the nod to form a government, his first challenge will be to try to form a coalition and present a plan of government that can win votes of confidence in both houses of Parliament. That's no easy task given his aggressive power-grab has alienated even some within his own party.

Then he has to get to the work of kick-starting Italy's economy, creating jobs and enacting sorely needed electoral reforms to make Italy more governable.
