David Cameron and his fellow European leaders have been playing with Lego at a summit on the future of the EU.
The Danish Prime Minister, Lars Løkke Rasmussen, revealed that they took part in a building challenge using the toy on Thursday.
He reportedly told a press conference that he beat Mr Cameron in their attempt to make a duck out of the miniature bricks.
Lucy Fisher, a senior political correspondent at The Times, wrote on Twitter that the Prime Minister admitted that he “struggled”, with his Icelandic counterpart adding: “It looked more like a dog than a duck.”
The Prime Minister of Finland, Juha Sipilä, reportedly went on to joke about them forming a band.
Political opponents were quick to pick up on Mr Cameron’s alleged failure.
“How can Cameron 'build a better Britain' when he can't even build Lego?” John Prescott quipped on Twitter.
The Prime Minister is attending the Northern Future Forum summit in Iceland with European leaders to discuss proposals on reforming the EU.
Discussions over Britain's proposals for EU reform have been underway with officials in Brussels since June and Mr Cameron has said he will provide details of his proposals to fellow EU leaders in a letter to European Council president early in November, before substantive talks between national leaders start at a Brussels summit in December.
