Listen to leader in town centre (5)
I believe the answer is:
heart
'centre' is the definition.
('heart' can be a synonym of 'centre')
'listen to leader in town' is the wordplay.
'listen to' becomes 'hear' (I've seen this before).
'leader in' indicates taking the first letters.
The first letter of 'town' is 't'.
'hear'+'t'='HEART'
(Other definitions for heart that I've seen before include "Earth (anag) -- compassion" , "Centre; valour" , "Feeling" , "Middle" , "one needs to beat" .)
