Prime minister from valley cycling westwards (4)
I believe the answer is:
eden
'prime minister' is the definition.
(Anthony Eden, UK PM 1955-57)
'from valley cycling westwards' is the wordplay.
'from' becomes 'e' (I've seen this in other clues).
'valley cycling' becomes 'ned' (I am not sure about this - if you are sure you should believe this answer much more).
'westwards' says the letters should be written backwards (letters go right to left or from 'east' to 'west').
'ned' reversed gives 'den'.
'e'+'den'='EDEN'
Can you help me to learn more?
(Other definitions for eden that I've seen before include "The first garden" , "Place of complete bliss" , "happy state" , "Genesis garden" , "heavenly spot" .)
