Italian Prime Minister Matteo Renzi said on Monday that Brexit would hurt more Britain than the EU.

"I hope Britain remains inside the EU, but if it leaves, the consequences will be worse for British citizens than for European ones. If Great Britain leaves, the main problem will be for the UK, its businesses and its citizens," he said.

Britain's Prime Minister David Cameron said on Saturday that the referendum will take place on June 23. Cameron secured a deal with the EU, which includes changes to migrant welfare payments, safeguards that Britain would not be a part of the Eurozone and safeguards for Britain's financial sector.
