Committee to criticise Spanish article (5)
I believe the answer is:
panel
'committee' is the definition.
(I know that panel is a type of committee)
'criticise spanish article' is the wordplay.
'criticise' becomes 'pan' (informal term meaning to criticise heavily).
'spanish article' becomes 'el' (the definite article 'the' in Spanish).
'pan'+'el'='PANEL'
'to' acts as a link.
(Other definitions for panel that I've seen before include "Body section" , "Quiz team; part of door" , "Talk show group" , "Interviewing group" , "Team of judges" .)
