Trouble as peacekeepers on holiday? (6)
I believe the answer is:
unrest
'trouble' is the definition.
(I've seen this before)
'peacekeepers on holiday?' is the wordplay.
'peacekeepers' becomes 'un'.
'on' is a charade indicator (letters next to each other).
'holiday?' becomes 'rest' (rest can mean a holiday or break).
'un'+'rest'='UNREST'
'as' is the link.
(Other definitions for unrest that I've seen before include "Turmoil, disquiet" , "State of discontent" , "State of rebellion" , "Feeling of anxiety or turmoil" , "State of uneasiness" .)
