Leaders of about 20 political parties have come together in the national capital to discuss the challenge posed by the alleged vulnerabilities in voting machines and their management. A delegation will also meet the Election Commissioners later in the day.In his firm message to the poll panel, Pranab Mukherjee said he had been a firm believer in the country’s institutions and “it is my considered opinion that it is the ‘workmen’ who decide how the institutional ‘tools’ perform.”“The safety and security of EVMs which are in the custody of the ECI is the responsibility of the Commission. There can be no room for speculations that challenge the very basis of our democracy. People’s mandate is sacrosanct and has to be above any iota of reasonable doubt,” he said.
