Rajkot: Buoyed by additional supply of Narmada water, Rajkot Municipal Corporation (RMC) has set up hoarding boards thanking Chief Minister Anandiben Patel and water supply minister Vijay Rupani for ensuring enough water for the city when local resources have gone dry. But opposition Congress termed it a publicity drive of the ruling BJP when the civic body goes to poll later this year and bypolls in two wards are already going on.
