On Tuesday Guido posted a graph displaying an inverse correlation: every time Gordon showed a whiff of recovery the value of the pound went into free fall. Whenever Labour goes up in the polls the pound goes down on the exchanges.

Well it seems last night the Newsnight economic team not only copied the concept, but Emily Nomates’s graphic too – the start dates and margins are identical to Emily’s original graph.

Nice to know where the BBC’s great and good come for an economics lesson.
