Report of people looking over PM's country retreat (8)
I believe the answer is:
chequers
If this is the answer I cannot explain how the clue works.
Can you help me to learn more?
(Other definitions for chequers that I've seen before include "Contrasting pattern" , "Official country residence of the British Prime Minister" , "country retreat in 21 [BUCKS]" , "PM's country house" , "Bucks residence" .)
