ROME (Reuters) - Mayoral elections in Italy's largest cities on Sunday and Monday are expected to illustrate Matteo Salvini's weakening grip of the right and see centre-left wins in the most high-profile contests.
A parliamentary by-election in the Tuscan city of Siena will also be closely watched because it holds the key to the future of Democratic Party (PD) leader Enrico Letta, who is one of the candidates.
