Former Union Minister RPN Singh joined the Bharatiya Janata Party (BJP), soon after quitting Congress on Tuesday.
In a major setback to Congress just ahead of the Uttar Pradesh Assembly election, the Jharkhand in-charge and ex-MP from Kushinagar constituency took to Twitter to inform of his joining.
"This is a new beginning for me and I look forward to my contribution to nation-building under the visionary leadership and guidance of Prime Minister Narendra Modi, BJP President JP Nadda and Home Minister Amit Shah," he said after resigning from the Congress party.
"Today, at a time, we are celebrating the formation of our great Republic, I begin a new chapter in my political journey. Jai Hind," he wrote on Twitter as he posted his resignation letter addressed to Sonia Gandhi.
Prior to the resignation, Singh had also changed his Twitter Bio from: "My motto India, First, Always. AICC in-charge, Jharkhand, Spokesperson Congress party, Former Minister of State for Home Affairs", to "My motto India, First, Always."
Congress Spokesperson Supriya Shrinate slammed Singh over his resignation and said, "The battle which Congress party is fighting can be fought only with bravery... It requires courage, strength and Priyanka Gandhi Ji has said that coward people can't fight it."
