New Delhi: Stepping up the attack against the opposition parties ahead of the 2019 Lok Sabha polls, Prime Minister Narendra Modi on Saturday urged his supporters to take the 'main bhi chowkidar' (I too am watchman) pledge and said he was not alone in the fight against graft and social evils, drawing ridicule from Congress president Rahul Gandhi.

"Your Chowkidar is standing firm & serving the nation. But, I am not alone. Everyone who is fighting corruption, dirt, social evils is a Chowkidar. Everyone working hard for the progress of India is a Chowkidar. Today, every Indian is saying-#MainBhiChowkidar," the prime minister wrote on Twitter.

He also posted a short video to drive home his message. Soon after, Gandhi mocked Modi and tweeted, "Defensive tweet Mr Modi! You feeling a little guilty today" while a tagging a picture of Modi along with businessmen such as Vijay Mallya, Nirav Modi and Mehul Choksi, Anil Ambani and Gautam Adani.

The Congress president earlier alleged that Modi only served the interests of his industrialist-friends. Modi has often described himself as a "chowkidar" who would neither allow corruption nor get corrupted himself.

Gandhi has been repeatedly hurling the "chowkidar chor hai" (watchman is the thief) jibe at Modi to claim irregularities and favouritism in the Rafale fighter jet deal, a charge the BJP-led government has rejected.

Congress chief spokesperson Randeep Surjewala hit back at Modi accusing him of being the "only chowkidar who is a thief". "One who wears a suit worth Rs 10 lakh and who helps Bank fraudsters Modi-Mehul-Mallya, one who wasts public money to the tune of Rs 52,000 crore for his own propaganda, one who spends Rs 2,010 crore to travel to 84 countries on people's money and one who helped in theft of Rs 30,000 crore in rafale jet deal, only one Chowkidar is a thief," he said in a tweet in Hindi.
