Proposal got doctor into trouble (6)
I believe the answer is:
motion
'proposal' is the definition.
(proposal at a meeting)
'doctor into trouble' is the wordplay.
'doctor' becomes 'mo' (medical officer).
'trouble' indicates anagramming the letters.
'into' with letters rearranged gives 'tion'.
'mo'+'tion'='MOTION'
'got' acts as a link.
(Other definitions for motion that I've seen before include "Formal proposal put to a meeting" , "Old coin of Germany" , "Proposal to be voted on" , "Flow - proposal" , "Poet laureate - proposal" .)
