The Communist Party of India (Marxist) on Monday asked home minister P Chidambaram to explain how his letter to Buddhadeb Bhattacharya was leaked to the media while the West Bengal chief minister is yet to get it.
"The home minister owes an explanation for this partisan approach," the CPI-M politburo said in a statement, referring to the letter regarding the alleged role of armed cadres of the CPI-M.
"The media has reported in detail the contents of (the) letter... These reports appeared in the media Dec 25, after being briefed about its contents on the 24th.
"However, such a letter was not received by the chief minister till three days later on Dec 27 (Monday)."
"This is a strange way of communication between the union home minister and the chief minister of a state. The media is fully briefed about the letter even before the chief minister gets it.
"This shows that the purpose of the letter is to serve the political interests of the Trinamul Congress, which is part of the union government," the statement said, referring to the main opposition party in West Bengal.
