(Reuters) - Deputy finance ministers of G7 nations will hold a conference call at 1130 GMT on Friday to discuss Britain's vote to leave the European Union, a source familiar with the matter said.

Global financial markets plunged on the referendum result, on fears it would hit investment in the world's fifth-largest economy, threaten London's role as a global financial capital and foment uncertainty in the world's biggest trading bloc.
