A British exit from the European Union would be a serious risk to global economic growth, Group of Seven leaders said in a summit declaration on Friday, although German Chancellor Angela Merkel said the issue had not been discussed.
The statement will be welcomed by the British government, which has issued a series of warnings about the domestic cost of voters opting to leave the bloc in a June 23 referendum on EU membership.
"A UK exit from the EU would reverse the trend towards greater global trade and investment, and the jobs they create, and is a further serious risk to growth," G7 leaders said, in the only reference to the vote in a 32-page declaration.
