ROME _ An Italian news agency says Premier Silvio Berlusconi is heading to see Italy's president after he failed to get enough support in parliament to stay in power much longer.
ATHENS, Greece _ Power-sharing talks between Greece's prime minister and the opposition leader dragged on, with senior government officials saying a deal was close but European leaders ratcheting up the pressure for a resolution.
LONDON _ Stock markets pulled back from gains earlier after a vote in the Italian Parliament showed the prime minister has lost the support of the majority and called into question Rome's ability to rein in its debts.
