Rush wildly around, as a politician in anger (7)
I believe the answer is:
rampage
'rush wildly' is the definition.
(I've seen this before)
'a politician in anger' is the wordplay.
'politician' becomes 'MP' (Member of Parliament).
'in' means one lot of letters goes inside another.
'anger' becomes 'rage' (rage is a kind of anger).
'a'+'mp'='amp'
'amp' going within 'rage' is 'RAMPAGE'.
'around as' acts as a link.
I am not very happy about this link. Some or all of it may belong to another bit of the clue.
Can you help me to learn more?
(Other definitions for rampage that I've seen before include "Violent rush" , "Rage wildly around" , "Uncontrolled rush" , "Storm" , "Run wild" .)
