Chief Remoaner Blair was chairing a panel discussion on populism at California-based think-tank the Milken Institute’s global conference last week.
Among the speakers was Matthew Elliott, former chief executive of Vote Leave, the official Brexit campaign group.
Mr Elliott, now the editor of blog BrexitCentral, spoke about how a new consensus must be built around Britain’s decision to cut ties with Brussels.
He then firmly told Mr Blair: “You have to start accepting the basic principles of what the public have said, and actually listen to what they said, in this case, in the referendum.”
A stunned-looking Mr Blair then stumbles over his words, attempting four times to think of a rebuttal to Mr Elliott.
