Criminal at the forefront of a political party in India (6)
I believe the answer is:
vandal
But I can't explain it at all! Could you help me understand?
(Other definitions for vandal that I've seen before include "Wanton wrecker" , "Person who damages property maliciously" , "Person who maliciously damages things" , "Lout causing damage to property" , "Barbarian - wrecker" .)
