Hitchcock, say, would do this kind of political manoeuvre (6,6)
I believe the answer is:
direct action
'hitchcock say would do this kind of political manoeuvre' is the definition.
'direct action' can be an answer for 'kind of political manoeuvre' (industrial action). I am not certain of the remainder of the definition.
'do this kind of political manoeuvre' is the wordplay.
'do' becomes 'direct' (directing is a kind of doing).
'this kind of political manoeuvre' becomes 'action' (I can't explain this - if you can you should give a lot more credence to this answer).
'direct'+'action'='DIRECT ACTION'
Can you help me to learn more?
(Other definitions for direct action that I've seen before include "Protest" , "sabotage?" , "striking, say - with 4a" , "protests" , "strikes, say" .)
