Binge drinking's ending in Conservative leader being axed (4)
I believe the answer is:
orgy
'binge' is the definition.
(I know that binge can be written as orgy)
I can't explain the remainder of the clue.
Can you help me to learn more?
(Other definitions for orgy that I've seen before include "Unrestrained revel" , "Excess" , "Wild revel" , "Bacchanal" , "Drunken revel" .)
