Examination panel look first and speak later (12)
I believe the answer is:
inspectorate
'examination panel look' is the definition.
I can't judge whether this defines the answer.
'first and speak later' is the wordplay.
'first and' becomes 'inspect' (I can't explain this - if you can you should give a lot more credence to this answer).
'speak' becomes 'orate' (orating is a kind of speaking).
'later' means one lot of letters go next to another.
'inspect'+'orate'='INSPECTORATE'
Can you help me to learn more?
(Other definitions for inspectorate that I've seen before include "Ofsted, for example" , "custodians" , "group of investigators" , "examiners" , "Examining official's office" .)
