Proof about European politician's violent commotion (7)
I believe the answer is:
tempest
'violent commotion' is the definition.
'tempest' can be an answer for 'commotion' (I've seen this in another clue). I am not sure about the 'violent' bit.
'proof about european politician's' is the wordplay.
'proof' becomes 'test' (I've seen this in another clue).
'about' means one lot of letters goes inside another.
'european' becomes 'e' (abbreviation e.g. EU).
'politician' becomes 'MP' (Member of Parliament).
'e'+'mp'='emp'
'test' going around 'emp' is 'TEMPEST'.
Can you help me to learn more?
(Other definitions for tempest that I've seen before include "Pets met in violent storm" , "violent agitation" , "Violent windy storm" , "An angry storm as in Shakespeare play" , "Shakespeare play with storm scene" .)
