After weeks of controversy over Labour and Conservative costings – in which each side accused the other of dishonesty – the manifestos show that both parties had wildly exaggerated their rival’s plans.

There are three main tropes that UK political parties have used in past elections to square this circle without much political cost. They are a crackdown on tax evasion, efficiency savings in public services, and sharp cuts in welfare spending.
