David Cameron has "let Britain down" after failing to stop Jean-Claude Juncker from taking the European commission president job, shadow foreign secretary Douglas Alexander said.
There is nothing splendid about David Cameron's isolation today. His defeat has diminished and not enhanced his standing on the international stage.
He badly misjudged these negotiations and as a result has let Britain down. Europe needs to change, but the Prime Minister made a series of unforced and unnecessary errors.
Any pretence that the Prime Minister could convince 27 other European leaders to accept his wholesale redesign of the European Union has been stripped away by his defeat.
It should be no surprise that David Cameron failed to stop such a long-standing EU figure being nominated as European Commission president.
The PM's friends in Europe are bewildered that he would rather go down in flames than try for the best deal possible in the circumstances.
