Crossword Genius

Liberal candidate finally left a vague flyer (7)

Ross

I believe the answer is:

leaflet

'flyer' is the definition.
(I've seen this in another clue)

'liberal candidate finally left a vague' is the wordplay.
'finally' indicates one should take the final letters.
'vague' indicates an anagram.
The last letters of 'liberal candidate' are 'le'.
'left'+'a'='lefta'
'lefta' is an anagram of 'aflet'.
'le'+'aflet'='LEAFLET'

(Other definitions for leaflet that I've seen before include "Pamphlet or booklet" , "very little greenery" , "Small information sheet" , "Distribute small circulars" , "It may advertise" .)

I've seen this clue in The Telegraph.
