US President Barack Obama has said the UK vote to leave the EU raises longer term concerns about global growth. He said Brexit would freeze the possibilities of investment in Great Britain or in Europe as a whole. He appealed to the UK Prime Minister and other EU leaders to ensure an orderly process for the British
exit.
Mr Obama was speaking at a summit in Ottawa with the leaders of Canada and Mexico, aimed at strengthening economic ties between the three North American countries. Earlier, EU leaders warned that the UK must honour the principle of free movement of people if it wants to retain access to the single market.
