You can’t call him Miliband because of his brother, and you can’t call him Ed because of his soon-to-be Shadow Chancellor.
Sooner rather than later, somebody or the media will settle on the correct nomenclature for the Miliband the Younger.
This is my contribution: he should henceforth be known as Edmilb.
Edmilb is an anagram of LibDem. That’s what I think makes it apt.
What does anyone else think?
