Withhold quickly read page (5)
I believe the answer is:
skimp
'withhold' is the definition.
(I've seen this before)
'quickly read page' is the wordplay.
'quickly read' becomes 'skim' (I've seen this in another clue).
'page' becomes 'p'.
'skim'+'p'='SKIMP'
(Other definitions for skimp that I've seen before include "Be niggardly" , "Use less to economise" , "Limit in quality or quantity" , "Withhold" , "Cut corners" .)
