Karnataka Chief Minister and Congress main face in the poll-bound state, Siddaramaiah today berated a journalist for dragging UPA chairperson Sonia Gandhis name into the Mahadayi river water sharing issue. Siddaramaiah was reacting to Prime Minister Narendra Modis claim that Sonia Gandhi had in 2007 said that Mahadayi waters wont be shared with Karnataka. Decision on Mahadayi water has to be taken by the Prime Minister, not Sonia Gandhi, the CM said. At this point, the reporter asked: But did Mrs Gandhi really block process?. CM Siddaramaiah in a curt reply said, You dont understand the issue so keep quiet. PM Modi on Saturday blamed the Congress party for politicising the issue of Mahadayi river water sharing with neighbouring Goa. During a 2007 Goa Assembly poll campaign speech, then Congress President Sonia Gandhi had assured Goa that Mahadayi river water will not be shared, The Prime Minister said the Congress has shown its true colour by politicising the issue. Speaking at Goa The Congress was only showing its BJP president Amit Shah, on Sunday, suggested had Siddaramaiah government worked sincerely, farmers in Karnataka would have received water from Mahadayi river without a fuss. Speaking at a public rally in Karnatakas Belagavi, Shah said, Had Siddaramaiah worked properly, Mahadayi rivers water would have reached the fields of farmers in Karnataka. Bring B. S. Yeddyurappa to power and within six months, the Mahadayi water dispute issue will be resolved, he added. Karnataka and Goa have been at loggerheads for decades on the issue of sharing inter-state Mahadayi river water.
