President Obama reiterated America's desire for Britain to remain a key player in the European Union during his phone call with David Cameron today.
The call, during which the leaders discussed the Algerian hostage crisis, saw Mr Cameron outline his stance on Britain's role in Europe ahead of a keynote speech in Amsterdam, which was later postponed due to the kidnappings.
The White House confirmed: "The President underscored our close alliance with the United Kingdom and said that the United States values a strong UK in a strong European Union, which makes critical contributions to peace, prosperity, and security in Europe and around the world."
Centrica's boss warns an EU referendum risks "total destabilisation" for businesses; the Next chief suggests that view is "scaremongering."
There will be sympathy, yes. But will they agree with him? No.
Conservative MPs said their "achievable" proposals to change Britain's role in Europe do not represent an ultimatum to the Prime Minister.
