Very needy princess involved with Guy Chambers (8)
I believe the answer is:
indigent
'very needy' is the definition.
'indigent' can be an answer for 'needy' (synonyms). I am not sure about the 'very' bit.
'princess involved with guy chambers' is the wordplay.
I cannot quite understand how this works, but
'princess' could be 'di' (Princess Diana) and 'di' is found in the answer.
'involved' could be 'in' (to be involved in something is to be 'in' it) and 'in' is found in the answer.
'guy' could be 'gent' (I've seen this in another clue) and 'gent' is located in the answer.
No letters remain.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for indigent that I've seen before include "Poor enough to need help from others" , "Impoverished -- ending it (anag)" , "Badly off" , "Poor and needy" , "Impoverished, destitute" .)
