MILAN (REUTERS) - Italy's Economy Minister Pier Carlo Padoan said on Saturday (June 25) that Britain's vote to leave the European Union could lead to the Italian economy growing less than initially forecast, with a negative impact on public finances.

Italy, the euro zone's third largest economy, has posted weak growth since it emerged from a three-year recession at the start of 2015 and continues to lag the rest of the currency bloc.

"We have to be very clear: it can't be ruled out that, following Brexit, for reasons outside our control, the economic picture worsens and we will have less growth," Padoan told the Corriere della Sera daily in an interview.

"This will hit public finances. I hope it doesn't happen but it is probable."

The government's present forecast is for growth of 1.2 per cent this year. Italy's public debt, at around 133 per cent of gross domestic product, is the highest in the euro zone after Greece's.

Unicredit, the country's largest bank, said that following the British referendum it was slashing its 2017 growth forecast for Italy to between 0.2 and 0.7 per cent, down from a previous 1.2 per cent.

On Friday, the Italian economy ministry said Britain's decision could have a "limited" impact on growth.

Padoan told Corriere della Sera that to avoid the previously"unthinkable" risk that the British vote leads to other countries also leaving, the EU must now review its priorities. "Europe can no longer only worry about banks," he said, calling for "common policies that don't only regard banking union but also immigration, security and the fight against inequality."
