The Labour leader thanked US presidential candidate Mitt Romney for the name tag he gave him on a visit to Britain in July.
Some claimed the "Mr Leader" moniker showed Mr Romney did not know who the leader of the opposition was - or had at least forgotten his name. But Mr Miliband said the title "it has a certain ring to it."
