Edinburgh-based Hetherington, who works for Richard Murphy Architects, failed to impress in the first caramel week the series has ever had, with his showstopper – a hummingbird cake with caramel decorations – sealing the deal for his exit.

Tom’s unravelling began with the first of three challenges, the signature bake, when he failed to complete the millionaire’s shortbread.

Instead of offering judges Prue Leith and Paul Hollywood 18 identical bakes, he ran out of time and instead presented them with two large tins of his caramel concoction.

In a round that produced a number of impressive creations, judge Hollywood described Hetherington’s effort as “gooey, underbaked and with no crumb”.

Hetherington accepted that he had had an awful week, tweeting: “I came unstuck in #CaramelWeek So sorry to leave the tent, but honoured to have been a part of it all.”
