Leader of council ushered back outside with plan to make a passionate speech (7)
I believe the answer is:
declaim
'to make a passionate speech' is the definition.
I can't tell whether this definition defines the answer.
'leader of council ushered back outside with plan' is the wordplay.
'leader of' indicates taking the first letters.
'ushered back' becomes 'del' (I can't justify this - if you can you should believe this answer much more).
'outside' is an insertion indicator.
'with' says to put letters next to each other.
'plan' becomes 'aim' (aiming is a kind of planning).
The initial letter of 'council' is 'c'.
'c' put within 'del' is 'decl'.
'decl'+'aim'='DECLAIM'
Can you help me to learn more?
(Other definitions for declaim that I've seen before include "Spout" , "Deliver an impassioned speech" , "Make a rhetorical speech" , "Deliver (words) impressively" , "Rail against" .)
