MILAN (AP) — Three-time former Premier Silvio Berlusconi pledged Saturday that his Forza Italia party will be a “responsible opposition” to any new government headed by the Democratic Party leader Matteo Renzi, but expressed concern about what he called an “opaque” power grab.

Berlusconi was among the political leaders who met over two days in Rome with Italy’s president, who is trying to determine if Renzi has enough support to form a new government after he sidelined outgoing Premier Enrico Letta, a rival Democrat.
