Poll strategist Prashant Kishor on Thursday resigned as Principal Advisor to Punjab Chief Minister Amarinder Singh, saying "he's resigning in view of his decision to take a temporary break from public life".

"As you are aware, in view of my decision to take a temporary break from active role in public life, I have not been able to take over the responsibilities as your Principal Advisor. Since I am yet to decide on my future course of action, I write to request you to kindly relieve me from this responsibility," Kishor said in a letter to the Chief Minister.
