In a veiled attack on MNS chief Raj Thackeray, former Mumbai mayor Kishori Pednerkar on Wednesday said he has "heartburn" as his cousin and Shiv Sena president Uddhav Thackeray became the Maharashtra chief minister.

Without naming the Maharashtra Navnirman Sena (MNS) president, Pednekar said he was bad-mouthing his cousin the same way he was earlier doing against the BJP.
