Does this shock image reveal why business is booming at Aldi? Perhaps the discounter is on such a hot run at the moment because its crack marketing team is more on the ball than those of its rivals.

Bogof spies spotted this bit of guerrilla advertising near Bicester, where Aldi is obviously looking to steal a little of Lidl’s sponsorship limelight.

That’s one advantage of having joint group MDs - one can tend the shop while the other runs around in a balaclava defacing rivals’ signage.
