Siddaramaiah will become the longest-serving Chief Minister of Karnataka on January 7. He will surpass the record of D Devaraj Urs, who ruled the state from 1972 to 1977 and from 1978 to 1980. Siddaramaiah completed a full term from 2013 to 2018 and has now been holding the post since May 2023, amid the leadership tussle with DK Shivakumar.
