U.S. Secretary of State John Kerry will meet European Union foreign policy chief Federica Mogherini in Brussels and British Foreign Minister Philip Hammond in London on Monday, a senior State Department official said.
The trip comes as European Union and UK officials weigh the political and economic fallout from Friday's shock British >referendum vote in favour of leaving the 28-nation bloc .
The senior official said Kerry would stress the importance of other members not following Britain and further weakening the EU. U.S. President Barack Obama had urged voters in Britain -- long seen as Washington's closest European ally -- not to approve Brexit.
