Frank, Charlie and I would (6)

I believe the answer is:

candid

'frank' is the definition.
(I know that frank can be written as candid)

'charlie and i would' is the wordplay.
'charlie' becomes 'C' (phonetic alphabet: alpha, bravo, charlie etc.).
'i would' becomes 'I'd'.
'c'+'and'+'id'='CANDID'

(Other definitions for candid that I've seen before include "Blunt; frank" , "Frank and outspoken" , "Frank, forthright" , "Plain" , "Frank - and CID (anag)" .)

I've seen this clue in The Times.
