Shadow foreign secretary Douglas Alexander has said Labour had been "entirely consistent" since July in arguing for a real-terms cut in EU spending.
He said: "The Labour Party was consistent and clear in July that we thought the right approach for Britain, in fact the right approach for Europe, was to go for a real-terms cut.
"We support Britain's future in Europe but we also support the reform of Europe," he added.
