Labour target in jeopardy, high up (5)
I believe the answer is:
hydra
'labour target' is the definition.
The definition and answer can be both people as well as being singular nouns.
Maybe you can see a link between them that I don't see?
'in jeopardy high up' is the wordplay.
'in' indicates a hidden word.
'up' is a reversal indicator (in down clue: letters go upwards).
'ardyh' is hidden in the letters of 'jeopardy high'.
'ardyh' reversed gives 'HYDRA'.
Can you help me to learn more?
(Other definitions for hydra that I've seen before include "Nine-headed monster killed by Hercules" , "Many-headed foe of Hercules" , "Water monster" , "Multi-headed monster killed by Hercules" , "Persistent trouble" .)
