Starmer say repaired cistern given time (8)
I believe the answer is:
centrist
'starmer' is the definition.
I can't judge whether this definition defines the answer.
'repaired cistern given time' is the wordplay.
'repaired' indicates an anagram.
'given' indicates putting letters inside.
'time' becomes 't' (abbreviation).
'cistern' is an anagram of 'cenrist'.
'cenrist' enclosing 't' is 'CENTRIST'.
'say' is the link.
Can you help me to learn more?
(Other definitions for centrist that I've seen before include "A middle-of-the-road person in politics" , "One taking the middle ground" , "Politician who takes middle-of-the-road position" , "Moderate politician" , "Person who takes a middle-of-the-road political position" .)
