Which Tory MPs will repeat the porkie about ‘halving’ the deficit?

New year, new porkies from Conservative HQ. It has opened 2015 with a poster that involves a deception (above): ‘the defict halved’. It’s a relatively small deception: the deficit has been reduced by a third (see graph below) just as David Cameron was saying only a few weeks ago. But this poster makes a more important, and more depressing point: the Tory leadership is prepared to use dishonesty as a weapon in this election campaign.

Here’s how I suspect it all unravelled. George Osborne invented the porkie: that you can say ‘the deficit has been halved’ if, when challenged, you later claim that you’re referring not the deficit, but to a ratio: a deficit/GDP ratio. This is a valid metric, but it’s not “the deficit”.

This is not an argument about economics, but about language – and honesty in politics. Yesterday, in the Today programme, Robert Peston was asked about “the deficit”. “It’s £91 billion,” he said – as you’d expect.
