Leader of Opposition Rahul Gandhi has stepped up his attack on the Centre's E20 petrol policy, alleging that higher ethanol blending is damaging cars and two-wheelers and increasing expenses for consumers. But his latest video has triggered a political counterattack, with the BJP pointing to the car shown alongside him and claiming it is labelled E20-compatible. As the Congress vows to take up the E20 issue in a big way, the fuel policy is turning into another major political flashpoint between Rahul Gandhi and the Modi government.
