Leader’s position in group’s last run of gigs (10)
I believe the answer is:
presidency
'leader's position' is the definition.
'presidency' can be an answer for 'position' (presidency is a kind of position). I am unsure of the 'leader's' bit.
I cannot understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for presidency that I've seen before include "Top position" , "place at the top" , "Office at the top" , "US office" , "Monroe once took on" .)
