Disgruntled Raja Sansi Congress MLA Sukhbinder Singh Sarkaria furnished a reply to the Congress Legislature Party (CLP) leader Sunil Jakhar on Saturday.
He had been asked to reply to his September 29 letter to Congress president Sonia Gandhi, in which he had attacked state Congress chief Partap Singh Bajwa and had praised former chief minister Capt Amarinder Singh.
Sarkaria was charged with violating party discipline as he had released the letter to the media.
The CLP leader had been asked by the Congress high command to seek an explanation from Sarkaria by October 5. Jakhar had met the MLA on Wednesday.
Sarkaria handed over his reply in a sealed envelope to Jakhar's personal assistant at the CLP leader's official residence in Chandigarh. This was confirmed by Sarkaria, who went to Chandigarh to hand over the envelope personally.
Jakhar, who is New Delhi, could not be contacted. He is expected to go through the reply before forwarding it to the high command.
Sarkaria, on his part said, "I cannot disclose the contents of the reply as it is a party matter."
