The Tories are hoping the voters will swallow their “Long Term Economic Plan” slogan, though one adviser is literally stuffing it down throats. Last week saw Downing Street staff recreate the Great British Bake Off, with civil service boss Sir Jeremy Heywood playing the role of Mary Berry and judging the contest.

Raising money for Magic Breakfast – who provide 8,500 brekkies to school children every day – SpAd Daniel Korski’s entry was a cake emblazoned with the slogan, though that lost out to the elaborate gingerbread reconstruction of No 10 Deputy Head of Press Alan Sendorek.

Insiders blame rigid civil service impartiality for the the decision – Sir Jeremy’s loyalty must always be to the office and institution rather than the party in power. “I was robbed” says a source close to Korski.
