Sportsman unlikely to run against British member of parliament and head of state (4,6)
I believe the answer is:
fast bowler
'british member of parliament and head of state' is the definition.
I know nothing about this answer so I can't tell whether this works.
'sportsman unlikely to run against' is the wordplay.
'sportsman' becomes 'bowler' (I've seen this before).
'unlikely to run' becomes 'fast' (I've seen this before).
'against' is a charade indicator (letters next to each other).
'bowler' put after 'fast' is 'FAST BOWLER'.
Can you help me to learn more?
(Other definitions for fast bowler that I've seen before include "Cricketer" , "Sporting quickie?" .)
