No 10 accepts US warning
Downing Street has reaffirmed its preference for remaining within the EU after the Obama administration signalled growing concern about the possibility of the UK leaving.
After Philip Gordon, US assistant secretary for European affairs, said there could be negative consequences if Britain left the EU, a No 10 spokesman said: "The US wants an outward looking EU with Britain in it, and so do we."
The Financial Times reports Mr Gordon as saying: "We have a growing relationship with the EU as an institution, which has an increasing voice in the world, and we want to see a strong British voice in that EU.
"That is in America’s interests. We welcome an outward-looking EU with Britain in it."
Douglas Alexander, Labour’s Shadow Foreign Secretary, said: “There is today a real risk of Britain sleepwalking towards exit because of a Prime Minister motivated more by the need for party unity than by the interests of the country.”
