Berlusconi says accepts referendum result
In a statement issued after the close of voting, Berlusconi said "the decision of Italians is clear on all the issues in the vote."
"The government and parliament now have the duty to fully accept the result of the four referendums," he said.
Official figures showed an unusually high turnout and suggested that the votes would go overwhelmingly in favour of repealing Berlusconi-era legislation.
