Italian centre-left politician Enrico Letta has reached a deal to form a new government, raising hopes of ending months of political uncertainty triggered by February's inconclusive elections. Letta said on Saturday that the government, a coalition between his Democratic Party (PD) and Silvio Berlusconi's People of Liberty (PDL) party, will include one of the former prime minister's closest allies as deputy prime minister.
