Cunning as the Tories’ campaign team are, though, it seems they haven’t thought of everything. To illustrate the “chaos, instability, insecurity and uncertainty” that Jeremy Corbyn would “unleash on the country”, Messrs Hammond and Davis presented the Tories’ new billboard. It featured a photo of the Labour leader, superimposed over a bomb with the words “MORE DEBT” and “HIGHER TAXES” on it.

“CORBYN: NO BOMBS FOR OUR ARMY,” blared the warning at the top. “ONE BIG BOMBSHELL FOR YOUR FAMILY.”

Photographers snapped away. Someone, though, had forgotten to remind Mr Davis to take care when posing in front of billboards. Photos, after all, can be mischievously cropped.

Which is why there is now a picture in circulation that shows nothing but a scowling Conservative minister, a bomb marked “DEBT” and “TAXES”, and the words “HELL FOR YOUR FAMILY”.
