Politician identified as capable of promoting growth (5-8)
I believe the answer is:
green-fingered
'capable of promoting growth' is the definition.
I can't judge whether this defines the answer.
'politician identified' is the wordplay.
'politician' becomes 'green' (eg member of the Green Party).
'identified' becomes 'fingered' (I can't explain this - if you can you should believe this answer much more).
'green'+'fingered'='GREEN-FINGERED'
'as' acts as a link.
Can you help me to learn more?
(Other definitions for green-fingered that I've seen before include "Having aptitude at growing plants" , "Possessing natural gardening skills?" , "Having the knack of making plants grow well" , "Good at gardening" , "With a talent for growing things" .)
