Samajwadi Party corporator Bantu Yadav, who was shot at a week ago in the Uttar Pradesh capital, succumbed to his injuries on Saturday.
Yadav, a corporator from Ramteertha ward in Narhi, was shot at from point-blank range in the head while attending a funeral last week.
His assailant was arrested soon after and told police that he was given a contract by some builders to kill Yadav.
A panel of doctors conducted a post-mortem examination after which Yadav's body was handed over to his family.
Hundreds of supporters, party workers and relatives took part in his funeral procession.
Security was beefed up in the area to ensure that there was no violent reaction to the death.
A BJP corporator was also recently shot dead in Varanasi.
