He and his son left Shiromani Akali Dal (Taksali) & re-joined Shiromani Akali Dal on 13 February 2020 at the SAD Rajasanshi Rally in presence of Sukhbir Singh Badal. But after a couple of days, he left and rejoined the Shiromani Akali Dal (Taksali) again because he said he still felt annoyed with Badal.
