Italy's finance minister says whatever British voters decide, there's already a fracture with the European Union.
Minister Pier Carlo Padoan is being quoted as saying at a forum in Rome on Thursday that no matter what happens, it will be impossible to assert "let's pick up as if nothing" happened.
The Italian news agency ANSA quoted him as saying that as Britons vote to decide whether to exit or stay in the EU, that "the fracture has already happened and in a very clear-cut way." Padoan said the consequences will vary, depending on the outcome, but "there won't be the same path as if there hadn't been the referendum initiative."

Guests billed for Assange's show include Greece's ex-finance minister Yanis Varoufakis, musician Brian Eno and "former CIA officers." It is scheduled to run from 1900 GMT Thursday until early Friday morning, when referendum results are expected.
England soccer captain Wayne Rooney isn't following David Beckham's lead in announcing how he voted in the referendum about whether Britain remains in the European Union. Or even if he voted at all.
Asked Thursday if he voted, Rooney said, "I'd like to keep that private."
Speaking at England's training base north of Paris during the European Championship, Rooney said, "The option has been there for the players (to vote during the tournament) - I don't know which ones have, which ones haven't."

A sense of uncertainty seemed to hang over central Edinburgh in Scotland as voters pondered how a vote for Britain to leave the European Union might affect the Scottish independence movement.

Clayton Thomson, a 30-year-old bar manager, said Scottish nationalists might call another referendum if a "leave" vote takes Scotland and the rest of Britain out of the European bloc.

She said: "overall, I think discussions must now be continued with 28 (countries) if possible and otherwise with all countries - that would be 27 - but my hopes are pinned on it possibly being able to remain 28."
She noted that an already-scheduled EU summit starting next Tuesday will give countries "the opportunity to discuss all together and calmly how we continue to implement our agenda."

Foreign Minister Peter Szijjarto on Thursday described Britain as a "pragmatic voice" in the debate about the future of the EU, often in line with Hungary's vision of the 28-member bloc, adding that its exit would be "contradictory" from a political and economic perspective.

Polling firm Ipsos MORI says the "remain" camp enjoyed a four-point lead ahead of the vote. But the polling firm's chief executive, Ben Page, says 13 percent of those polled said they still might change their minds.
The poll of 1,592 people was conducted for the Evening Standard newspaper and was completed Wednesday night.
Page said Thursday that heavy rain in London may affect the vote, because the British capital is seen as a "remain" stronghold.

Among the offers: "We won't use any sun cream at the beach any more - out of solidarity with your sunburn!" And "we'll push through an EU directive banning foam on beer!"
Topping the list was an offer that would stick in any Germany soccer fan's throat: "Even we will recognize the Wembley goal!" That's a reference to England's third goal in its 1966 World Cup final victory, which Germans maintain didn't cross the goal line.
