Coordinate a policy broadcast (5)

I believe the answer is:

align

I'm a little stuck... Click here to teach me more about this clue!

'coordinate' is the definition.
(synonyms)

'a policy broadcast' is the wordplay.
'policy broadcast' becomes 'lign' (I can't justify this - if you can you should give a lot more credence to this answer).
'a'+'lign'='ALIGN'

Can you help me to learn more?

(Other definitions for align that I've seen before include "Adjust -coordinate" , "Bring (things) into a proper relationship" , "Place in a row" , "Come together in agreement" , "Put in order" .)

I've seen this clue in The Times.
