Posh politician, with passion, able to count up to six (6)
I believe the answer is:
umpire
'able to count up to six' is the definition.
I can't judge whether this definition defines the answer.
'posh politician with passion' is the wordplay.
'posh' becomes 'u' (abbreviation for upper-class - opposite to non-U).
'politician' becomes 'MP' (Member of Parliament).
'with' is a charade indicator (letters next to each other).
'passion' becomes 'ire' (ire is passionate anger).
'u'+'mp'+'ire'='UMPIRE'
Can you help me to learn more?
(Other definitions for umpire that I've seen before include "Sports official" , "Football official" , "Arbiter of cricket match" , "Adjudicator in games such as cricket, tennis etc" , "Impartial supervisor" .)
