Politician to tear off outside to meddle (6)
I believe the answer is:
tamper
'meddle' is the definition.
(I know that meddle is a kind of meddle)
I don't understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for tamper that I've seen before include "'Alter or falsify, documents perhaps (6)'" , "Destructively interfere (with)" , "Interfere (with something) without permission" , "Interfere or alter without authority" , "Mess damagingly (with)" .)
