Choudhary, who originally hailed from Bhimber Tehsil in Pakistan-occupied Kashmir before his family migrated to border village Chakroi in R S Pura sector, had won Suchetgarh assembly seat for the first time in 2008 and repeated the performance for the party in 2014.
Singh expressed gratitude to his voters and said the vote for him was "against the farm laws imposed by the BJP government on the farmers of the country against their will".
"The BJP went for aggressive campaigning bringing union ministers, chief ministers and national leaders to divert the attention of the voters from the real issues facing the public," Singh, who finally prevailed after a neck-to-neck fight with the BJP leader, said.
