After weeks of acrimony and public wrangling, the Aam Aadmi Party (AAP) finally expelled founder members Yogendra Yadav and Prashant Bhushan late on Monday night. The exit that Mr Yadav and Mr Bhushan had predicted weeks ago took place in stages. The two leaders were systematically removed from all party panels, and then served notice by a disciplinary committee that Mr Bhushan once headed.
