"The present situation of Congress in Delhi is because of PC Chacko," Goswami said.
They also said that a committee should be formed to probe leak of a personal letter written to Chacko by Sandeep Dikshit.
Earlier, speaking to ANI about the letter, Chacko said, "After reading the letter, I thought the Congress president should be aware of this letter. So, I have forwarded the letter to Congress president."
Chacko had said that only Sandeep Dikshit can tell why he wrote the letter.
"Whether any action or no action, these are all things to be decided in future," Chacko had said.
Chacko had written to Sheila Dikshit against her dissolving block committees. She passed away a few days later. Chacko had in August expressed his desire to step down.
