Clash of politicians after moving to centre (11)
I believe the answer is:
contretemps
'clash' is the definition.
(I know that contretemps is a type of clash)
'politicians after moving to centre' is the wordplay.
'politicians' becomes 'MPs' (Members of Parliament).
'after' means one lot of letters go next to another.
'moving' is an anagram indicator (letters are moved around).
'to'+'centre'='tocentre'
'tocentre' is an anagram of 'contrete'.
'mps' after 'contrete' is 'CONTRETEMPS'.
'of' acts as a link.
(Other definitions for contretemps that I've seen before include "Unexpected embarrassment" , "Prescott men (anag) - awkward moment" , "Minor difference" , "Inopportune happening" , "Awkward argument" .)
