Criticise the Spanish jury (5)
I believe the answer is:
panel
'jury' is the definition.
(I know that jury can be written as panel)
'criticise the spanish' is the wordplay.
'criticise' becomes 'pan' (informal term meaning to criticise heavily).
'the spanish' becomes 'el' ('the' in Spanish).
'pan'+'el'='PANEL'
(Other definitions for panel that I've seen before include "Board for instruments" , "Judging committee" , "that's sometimes beaten?" , "Group judging a contest" , "List of doctors" .)
