After spending almost a year in Indian hospitals, ailing Congress leader Priyaranjan Dasmunshi was sent to Germany for stem cell treatment at Duesseldorf on Friday night. The German hospital has informed that Dasmunshi will have to stay there for at least 10 days. At least nine people including his brother, Congress leaders, and an old-time personal assistant have taken visas to accompany the ailing leader. Wife Deepa also left for Germany but would return soon because of her engagements related to the Assembly by-elections.
