Consequences of bill on one politician (6)
I believe the answer is:
impact
'consequences' is the definition.
(thesaurus)
'bill on one politician' is the wordplay.
'bill' becomes 'act' (I've seen this in other clues).
'on' means one lot of letters go next to another.
'one' becomes 'I' (Roman numeral).
'politician' becomes 'MP' (Member of Parliament).
'i'+'mp'='imp'
'act' put after 'imp' is 'IMPACT'.
'of' is the link.
(Other definitions for impact that I've seen before include "The striking of one thing against another" , "Forceful consequence" , "Forcible contact; marked influence" , "The striking of one body against another" , "Impression" .)
