Congress leader Rahul Gandhi's "Bharat Jodo Yatra" was marred by a tragic incident on Sunday as Punjab Congress MP, Santokh Singh Choudhary, passed away due to a heart attack while participating in the march. Choudhary collapsed while walking and was rushed to a hospital in Phagwara, however, he died on the way. The two-time MP was taking part in the yatra in Phillaur, Jalandhar, when the incident occurred. The death of the MP has left the Congress in a state of shock and the yatra was halted following Chaudhary's death. Gandhi has reportedly gone to the hospital and the party has also cancelled a press conference scheduled for Sunday in Jalandhar.
