It should be no surprise that David Cameron failed to stop such a long-standing EU figure being nominated as European Commission president.
David Cameron said it was "a serious mistake" that European Union leaders did not work together to find an alternative candidate to Jean-Claude Juncker as European Commission President.
The nomination of Jean-Claude Juncker as the next European Commission President represents an "abject failure of leadership" for David Cameron, said Labour’s Shadow Foreign Secretary Douglas Alexander:

The outcome of today’s summit represents an abject failure of leadership for David Cameron.
David Cameron’s basic errors of statecraft and diplomacy have let Britain down.
His excuses will fool nobody, least of all his own backbenchers.
Defeat for David Cameron was not inevitable. Yet it was predictable. Because for the past four years he’s been burning bridges with our European allies when he should have been building alliances.
Jean-Claude Juncker's nomination was approved by European leaders by a margin of 26-2, with only David Cameron and Hungarian PM Viktor Orban opposed, said British officials.
The vote, which was insisted upon by Cameron, marked a break with a tradition of filling key roles by consensus.
David Cameron's final plea to fellow European leaders not to nominate Jean-Claude Juncker as European Commission President were ignored, says ITV News Europe Editor James Mates:
Cameron has been making last plea to fellow leaders not to make Juncker Commission President. He's been ignored: Juncker formally proposed.
European Council leaders have approved the nomination of Jean-Claude Juncker as president of the European Commission, Council president Herman van Rompuy announced on his official Twitter account.

Juncker, the former prime minister of Luxembourg, was nominated at a summit on Friday despite strong objections from David Cameron.
The centre-right Juncker must now appear before the European Parliament and win a confirmation vote set for July 16 on his policy agenda.
Prime Minister David Cameron told European leaders 'they could live to regret' allowing parties rather than politicians to pick the European Commission.
I've told EU leaders they could live to regret the new process for choosing the Commission President. I'll always stand up for UK interests.
David Cameron told German Chancellor Angela Merkel that allowing parties rather than politicians to pick the European Commission is "a worrying moment for Europe and Britain."
In brief talks with the German leader before the formal opening of today's meeting of European leaders, officials said the British Prime Minister said he would not negotiate over his opposition to the appointment of Jean-Claude Juncker as European Commission President.
"Nobody will leave today unsure that when the Prime Minister says something he means it and when he says something is a principle he sticks to it," said one UK official.
A former cabinet minister has praised David Cameron's stance on Jean-Claude Juncker's appointment and claimed that isolation in Brussels was not a cause for concern.
Writing on his blog John Redwood, now a Conservative backbencher said: "To those who say Mr Cameron should not have sought to block Mr Juncker because he could not win, I say you are wrong."
The well known Eurosceptic added: "The battle over Mr Juncker was but the first skirmish in a long negotiation of a new relationship for the UK with the rest of the EU."
"If the rest of the EU continue to be so unsympathetic to UK requirements, more UK voters will draw their own conclusions about the desirability of our continued membership."
Labour leader Ed Miliband said it would "a total and utter humiliation" for David Cameron if Jean-Claude Juncker was appointed to the role of European Commission president.
He said: "Instead of building alliances in Europe, David Cameron burns our alliances and it's Britain that loses out."
