The new Foreign Secretary, Boris Johnson, has been booed by some of the guests at a French Embassy reception in London.

In his first public speech in his new role, Mr Johnson told the audience at the French Ambassador's residence that Anglo-French intergovernmental relations would be strengthened as the UK moves to leave the EU.

It was not clear whether the booing came from British or French guests, or both.

Mr Johnson stressed that the United Kingdom was in no sense leaving Europe, only the European Union.
