Rahul Gandhi on Wednesday resigned as president of the main opposition Congress, taking responsibility for the party’s second-straight landslide defeat to Hindu nationalist Prime Minister Narendra Modi in India’s national elections, AFP reports.

“Accountability is critical for the future growth of our party. It is for this reason that I have resigned as Congress president,” Gandhi said in a statement posted on his official Twitter account.

Gandhi, who was seeking to become the fourth member of his family dynasty to become prime minister, had been Congress president since December 2017.
