However, Malviya deleted the tweet, post social media uproar.
Following this, the BJP leader in his response to the election-governing body, claimed that the tweet was based on a flash taken out by a leading TV channel, thereby downplaying the possibility of an information leak.
"I wish to reiterate that I firmly believe in the exclusive constitutional domain of the Election Commission to conduct free and fair elections in the country, and also in the confidentiality and secrecy mandated upon it in process of doing so. It is my kind submission that my tweet was in no way intended to infringe upon the constitutional mandate of the Election Commission," Malviya clarified.
Meanwhile, a local media in Karnataka also announced similar dates, following updates from the aforementioned leading channel, as per their clarification.
However, the national TV channel clarified that no information leak had taken place.
On a related note, the 224-member Karnataka Assembly will go to polls on May 12, and counting of votes will be held on May 15.
