I'm a little stuck... Click here to teach me more about this clue!

'tail end' is the definition.
('stern' can be a synonym of 'tail end')

(Other definitions for stern that I've seen before include "Severe and unremitting: area of a ship" , "Rear of a vessel" , "Strict, grimly serious" , "Rear end" , "Poop" .)

I've seen this clue in The Telegraph.
