Actor Kangana Ranaut who never shies away from taking 'Panga' from anyone on Friday said that she has a natural instinct to challenge the authority of powerful people.

"I have never been intimidated by any powerful person and authority. I have a natural instinct to challenge authority and to test them, and it's very natural. Authority asks you for a certain submission, certain surrender. For that, it's very important to test the authority," said Ranaut.
