What some meetings need to be when Queen gets to speak (7)
I believe the answer is:
quorate
'what some meetings need to be' is the definition.
(quorate means with a valid number of attendees)
'queen gets to speak' is the wordplay.
'queen' becomes 'qu'.
'gets' says to put letters next to each other.
'to speak' becomes 'orate' (orating is a kind of speaking).
'qu'+'orate'='QUORATE'
'when' acts as a link.
(Other definitions for quorate that I've seen before include "Having sufficient numbers for meeting" , "With enough members present to function" , "Having enough people" .)
