Bengaluru, June 28 -- Karnataka chief minister Siddaramaiah on Friday dismissed reports of internal rift within the ruling Congress and sought to downplay his cabinet colleague KN Rajanna's remarks indicating a possible leadership change in the state. It came a day after cooperation minister Rajanna said there will be a political development in the state after September and that there were many power centres in the Karnataka Congress. "There is no internal dispute in the party. Minister Rajanna said that there may be developments in state politics. He did not say that such and such things will happen. It would be better to ignore his statement," Siddaramaiah said. When asked further about Rajanna's remarks, which were perceived as speculation of a possible leadership change, Siddaramaiah downplayed his colleague's statement, saying: "Did he say there will be a change in the chair?" Rajanna, considered close to Siddaramaiah, on Thursday told reporters that the Congress in Karnataka now has "too many power centres" compared to the earlier party-led government during 2013-2018 when there was just one. Deputy chief minister DK Shivakumar, who has long been seen a strong contender for the CM's post, refrained from commenting on Rajanna's remarks. "I have to speak to him. I don't know what that is about,"he said. On a question on Rajanna's claim that there are many power centres in the party, he said: "You should ask him."...
