English politician connects drains (7)
I believe the answer is:
empties
'drains' is the definition.
(I've seen this before)
'english politician connects' is the wordplay.
'english' becomes 'E' (abbreviation).
'politician' becomes 'MP' (Member of Parliament).
'connects' becomes 'ties' ('tie' can be a synonym of 'connect').
'e'+'mp'+'ties'='EMPTIES'
(Other definitions for empties that I've seen before include "Vacates" , "Bottles after the contents have been poured out" , "Returned bottles" , "drains" , "Dead men" .)
