The first 'Pravasi Bharatiya Divas' convention in physical mode since 2019 will be held in Indore in Madhya Pradesh from Sunday, an official said. The 17th edition of the PBD convention, which will take place over three days under the theme 'Diaspora: Reliable partners for India's progress in Amrit Kaal', will see more than 3,500 members from 70 nations taking part, he said. Pravasi Bharatiya Divas is celebrated on January 9 to mark the arrival of Gandhiji in Mumbai from South Africa on that day in 1915, while the PBD convention, since 2015, is organised every two years to mark the contribution of overseas Indian community to the development of the nation.
