Welcoming the action against Tharoor, KPCC President V M Sudheeran said it was an "appropriate decision."
In a statement posted on Twitter, Tharoor said he accepted the AICC's decision, adding he would have welcomed an opportunity to respond to the charges against him.
"While I have not yet seen the KPCC complaint referred to and while I would have welcomed an opportunity to respond to it and draw the attention of the AICC leadership to the full range of my statements and writings on contemporary political issues, I am now treating this matter as closed and have no further comment to make," he said.
Expressing deep resentment to his repeated praise of Modi and his initiatives like "Swachh Bharat" campaign, the KPCC had last week sought "appropriate action" from AICC against Tharoor.
The report held that Tharoor's adulatory statements about Modi had hurt Congress workers in Kerala, who had worked sincerely and tirelessly for his victory from Thiruvananthapuram Lok Sabha seat twice.
Though Tharoor had persistently held that his endorsement of "Swachh Bharat" mission neither meant that he approved the "Hindutva agenda" of BJP nor that he was moving closer to the saffron party, he chose to react sarcastically to the KPCC's move, which further antagonised sections in the party in the home state.
