New Delhi: The procedure to appoint dealers for around 50,000 petrol pumps have been halted by state-run oil companies after the recent announcement of the election schedule, sources said. Indian Oil Corp (IOC), the country's top refiner, Hindustan Petroleum Corp Ltd (HPCL) and Bharat Petroleum Corp Ltd (BPCL) advertised petrol pump dealership opportunities for about 78,500 locations across the country in November last year. Applications have been received for around 95 percent of all advertised locations, out of which 56 percent obtained multiple applications and 39 percent received single application.
