Point to new prime kingdom (6)
I believe the answer is:
empire
'kingdom' is the definition.
(I've seen this in another clue)
'point to new prime' is the wordplay.
'point' becomes 'e' (compass point).
'to new' indicates an anagram.
'prime' is an anagram of 'mpire'.
'e'+'mpire'='EMPIRE'
(Other definitions for empire that I've seen before include "Large organisation run from one point" , "Former British-ruled countries" , "Group of states ruled by one monarch" , "The Romans, Byzantines and Russians all ruled one" , "Widespread political or industrial organisation" .)
