Former AAP MLA from Rajouri Garden, Jarnail Singh, died on Friday morning of Covid-related complications.
He had been under intensive care at a super-speciality hospital here for over nine days, his family members said.
Singh had resigned from his seat in the Delhi assembly to contest the 2017 assembly polls in Punjab.
Delhi Chief Minister Arvind Kejriwal and his deputy Manish Sisodia also condoled the demise.
“Deeply saddened by the untimely demise of former Delhi MLA Sh Jarnail Singh ji. May God bless his soul. He will always be fondly remembered for his contributions to society,” Kejriwal said in a tweet.
Sisodia remembered Singh as someone who fought for justice for the victims of 1984 anti-Sikh riots.
“The news about the demise of Jarnail Singh, a former colleague in Delhi Assembly is extremely sad. A voice which fought for justice for the victims of 1984 genocide has left us,” he said in a tweet in Hindi.
