See Romeo's revolutionary supporter for bigger prize (8)

Ross

I believe the answer is:

rollover

'bigger prize' is the definition.
(as in a rollover jackpot)

'see romeo's revolutionary supporter' is the wordplay.
'see' becomes 'lo' (archaic exclamation meaning 'look!').
'romeo' becomes 'r' (phonetic alphabet: alpha, bravo, charlie etc.).
'revolutionary' is a reversal indicator (letters revolve around).
'supporter' becomes 'lover' ().
'lo'+'r'='lor'
'lor' in reverse letter order is 'rol'.
'rol'+'lover'='ROLLOVER'

'for' is the link.

(Other definitions for rollover that I've seen before include "Accumulative addition of unwon lottery prize money" , "Prize money taken forward" , "accumulated prize money" , "Surrender" , "Chance for an even bigger Lotto jackpot" .)

I've seen this clue in The Telegraph.
