Conservatives with no time for principles (8)
I believe the answer is:
theories
'for principles' is the definition.
(I've seen this before)
'conservatives with no time' is the wordplay.
'conservatives' becomes 'tories' (Tory is an example).
'with' indicates putting letters inside.
'no time' becomes 'he' (I can't justify this - if you can you should give a lot more credence to this answer).
'tories' going around 'he' is 'THEORIES'.
Can you help me to learn more?
(Other definitions for theories that I've seen before include "General principles or possibilities" , "Ideas or suppositions" , "premises?" , "Assumptions" , "Set of principles on which practices are based" .)
