Prodi confident check of votes will confirm victory
Returns released on Tuesday by the Interior Ministry gave the centre-left a slim majority in both houses of parliament. Berlusconi, though, has refused to concede defeat and challenged Prodi's victory claim, demanding a recount.
Berlusconi said he would concede only after Prodi is confirmed the winner after all the checks are carried out on the voting, which he says was marred by "irregularities."
