Admission from Conservative in partying cases (6)
I believe the answer is:
access
'admission' is the definition.
(I've seen this in another clue)
'conservative in partying cases' is the wordplay.
I cannot really understand how this works, but
'conservative' could be 'c' (UK political abbreviation) and 'c' is present in the answer.
an anagram of 'cases' is 'acess' which is within the left over letters.
This accounts for all the letters.
This may be the basis of the clue (or it may be nonsense).
'from' acts as a link.
Can you help me to learn more?
(Other definitions for access that I've seen before include "Means of approach or entry" , "The right to use something or see someone" , "Admission" , "Way of entering or leaving" , "OK to go in" .)
