Romano Prodi has rejected calls from his rival Silvio Berlusconi to form a grand coalition spanning Italy’s political spectrum. Prodi’s centre-left alliance has narrowly taken each house in the Parliament. But the electoral margin in both is tiny – 25,000 votes in the Lower House and only two seats in the Upper. Berlusconi is demanding a recount, and has suggested a system of shared government as a way forward. But despite his wafer-thin majority, Romano Prodi insisted he would have the authority to govern Italy for the next five years. Italy’s political future, however, remains uncertain.
