The 53-year-old's decision to quit the Cabinet was not unexpected.
Karnataka Minister for Kannada, Culture, and Tourism CT Ravi has tendered his resignation, days after being appointed BJP national General Secretary, sources close to him said on Sunday.
The four-time MLA from Chikkamagaluru submitted his resignation on Saturday to Chief Minister B S Yediyurappa.
They added that the Minister, who was appointed to the party position at the national level on September 26, is slated to fly to Delhi on Monday to meet the BJP Central leaders.
CT Ravi posted on Twitter one of the popular verses of "Mankuthimmana Kagga", written by famous Kannada litterateur D V Guddappa.
"Nothing stops when a person dies. The seasons continue to change. Time may grieve for some time. From the soil in which the dead are buried, rises the sprout of grass. Earth is pregnant again with new life. Nature is in a constant state of cultivation - Mankutimma," the Minister wrote.
The 53-year-old's decision to quit the Cabinet was not unexpected.
