How much did Harriet Harman’s infamous pink bus cost the Labour Party? Service Graphics invoiced them £4,742 “to produce and install Pink graphics” on the “Woman to Woman Bus”. That ends the debate about whether it was pink, magenta or cerise.

Despite him barely ever turning up, Labour blew £223,572 on David Axelrod’s firm AKPD. They spent another £563,973 on polling from Greenberg Quinlan Rosner, and £184,609 on Michael Sheehan’s debate coaching. There’s no price on laughter.
