Skip American politician being caught by cleaner (8)
I believe the answer is:
dumpster
'skip american' is the definition.
(an American term for a skip)
'politician being caught by cleaner' is the wordplay.
'politician' becomes 'MP' (Member of Parliament).
'being caught by' means one lot of letters goes inside another.
'cleaner' becomes 'duster' (dusting is a type of cleaning).
'mp' going inside 'duster' is 'DUMPSTER'.
(Other definitions for dumpster that I've seen before include "Perhaps skip" , "bin" .)
