EU foreign affairs head Federica Mogherini will hold talks Friday with British, French and German leaders to discuss ongoing negotiations on Iran's contested nuclear programme, her office said.
Mogherini will meet Prime Minister David Cameron, President Francois Hollande and Chancellor Angela Merkel on the sidelines of an EU leaders summit in Brussels, a spokeswoman said.
The meeting comes as talks with Iran continue on a deal which would allow Tehran to develop nuclear power but prevent it from getting atomic weapons.
