Patna: Chief minister Rekha Gupta has gone to Bihar for a three-day election campaign from Monday evening, marking her third visit to the state in recent times. "Gupta will hold public meetings, roadshows and interactive programmes in 12-15 assembly constituencies," said an official at CM's office. She will return on Nov 6. Meanwhile, AAP Delhi convener Saurabh Bharadwaj hit out at BJP, saying, "Delhi is choking under blanket of poisonous air, yet BJP ministers are busy campaigning in Bihar instead of addressing the crisis." Accusing AAP of making "irrational statements", Delhi BJP chief Virendra Sachdeva said, "The pollution in the national capital is slightly concerning but residents are well aware that the city's air quality has improved over the past few years."
