As a result of the vote, Berlusconi has avoided being forced to resign. But, as even some of his allies noted in the runup to the debate, he will find it difficult to lead the country with such a razor-thin majority.
Berlusconi's main ally, the anti-immigrant Northern League, and its leader, Umberto Bossi, who are riding high in the polls, would prefer an early election to resolve the foreseeable stalemate. Given their leverage over Berlusconi, it is likely they will get one, even if they have to wait until spring.
In the meantime, Italy's prime minister will remain embattled. On 11 January, the constitutional court is to rule on a law that grants Berlusconi temporary immunity from prosecution. If the decision goes against him, he will return to court to face charges of having bribed his former offshore legal adviser, David Mills.
Successive scandals have virtually paralysed his administration, and there is growing discontent in Italy over the slow pace at which its economy is recovering from the global recession. The jubilation on the government benches that greeted today's result is unlikely to endure.
