Prime Minister Narendra Modi on Tuesday flew by a seaplane from the Sabarmati river here to Dharoi in Mehsana district on the last day of the election campaign in Gujarat.The Bharatiya Janata Party said it was "the first-ever flight by a seaplane in the country". "Gujarat witnesses a seaplane takeoff from the Sabarmati riverfront. I will fly to Dharoi Dam via a seaplane and then pray at Ambaji," Modi said in a tweet.In the evening, Modi will fly back to Ahmedabad by the same plane.The Ahmedabad administration on Monday refused permission both for Modi's and Congress leader Rahul Gandhi's roadshows in the city. Modi drew the attention of the people towards the development work done by the BJP, which has ruled Gujarat since 1995. He tweeted: "With air, roads and rail connectivity, our government is making efforts for harnessing waterways. All this is for 125 crore Indians. "The transformation across Gujarat is for everyone to see. Sadly, Congress' notion of development is making a quick buck and that is why they are unable to see any change for the better," he added.The BJP is seeking a fifth straight term in the state, whose second and final phase of polling for Assembly elections will be held on Thursday. The first phase took place on December 9.The vote count is due on December 18.
