Italian Premier Silvio Berlusconi resigned today, but he pledged to form a new government in a bid to strengthen a coalition left weakened by electoral defeat and concerns about a slow economy.
His resignation ends his 4-year-old government, Italy's longest-serving since World War II. Berlusconi had been under pressure to resign since his party suffered a stinging defeat in regional elections this month.
He submitted his resignation to Italy's president but said he was confident a new government would relaunch his center-right coalition.
Berlusconi has been struggling to hold his government together, and a senior coalition partner, the National Alliance, threatened Tuesday to quit the government.
The government probably could not have survived if the alliance's five ministers had resigned.
