Blears jumps ship as Labour sinks
This is, of course, referring to Hazel Blears' resignation as communities secretary.
However I've always thought that someone who 'jumps ship' doesn't just leave one ship but joins another (metaphorically speaking).
To an extent, the Cambridge Idioms Dictionary (2nd Edition) agrees with me, saying:
if you jump ship, you leave a job or activity suddenly before it is finished, especially to go and work for someone else
So before reading the full story, I took thelondonpaper's headline to mean that Blears had jumped one ship (the Labour Party) to join another (probably the Conservative Party). I was, obviously, wrong.
And if you consider the literal meaning of 'to jump ship' - "to leave a ship without permission while it is temporarily in a port in the middle of a trip" (Cambridge Dictionary of American Idioms) - there's no reason to involve a second 'ship'.
So why do I feel like it was a bad choice of headline?
