The Chamber of Trade and Industry (CTI) has appealed to senior Congress leader Sonia Gandhi to defer the party’s proposed mega rally at Delhi’s Ramlila Maidan on November 1, citing the potential disruption to business during the peak Diwali shopping season. In a letter to Sonia Gandhi, the traders’ body warned that the rally could affect business worth Rs 10,000-12,000 crore across 20 major markets in the national capital.
