Information provided by the official Prime Minister's Office website and the biography published by the 'Election' website confirms the claim.
The information on the PMO website states that Prime Minister Narendra Modi served as Chief Minister of Gujarat with his term spanning from October 2001 to May 2014. He also won the subsequent parliamentary elections in 2014 and 2019.

He had contested in the parliamentary elections in 2014 and 2019 and he won both the elections.
