Shiv Sena founder Bal Thackeray was on medication, including steroids, for lung and heart ailments since November-December 2007, said Dr Jaleel Parkar, who treated him, before the Bombay High Court today.

Dr Parkar was being examined and cross-examined as the High Court is hearing dispute between Thackeray's sons Uddhav and Jaidev over the late leader's will. The will does not bequest anything to Jaidev, Thackeray's estranged son.
