Support colleague in accordance with the law (7)
I believe the answer is:
legally
'accordance with the law' is the definition.
I can't tell whether this defines the answer.
'support colleague' is the wordplay.
'support' becomes 'leg' (leg is a kind of support).
'colleague' becomes 'ally' (ally can mean a colleague or associate).
'leg'+'ally'='LEGALLY'
'in' acts as a link.
Can you help me to learn more?
(Other definitions for legally that I've seen before include "Lawfully" , "As regards the law" , "according to the national regulations" , "within the law" , "abiding by the rules" .)
