Kolkata, Feb 8 (IANS): Coming down heavily on the Mamata Banerjee government, West Bengal Governor Keshari Nath Tripathi on Thursday asked them to stop throwing mud at the governor's office and carry out an introspection of their own actions.

"Enough harsh words have been said. They should stop throwing mud on the office of the Governor.They should go to the washroom. Look at their faces in the mirror and remove those dirt from their faces," Tripathi said in response to state Parliamentary Affairs Minister Partha Chatterjee's claim that the Governor had flouted the Constitution.

The controversy erupted on February 6, when the state ruling party attacked the Governor after the Additional Chief Secretary to Tripathi wrote a letter to the Malda Divisional Commissioner asking him to hold a meeting on administrative matters.

The Trinamool Congress accused the Governor of violating the federal structure by bypassing the state government and its MPs tried to raise the issue in the Rajya Sabha forcing adjournments.

Chatterjee, who is also Trinamool Secretary General, on Wednesday condemned Tripathi's move as "unconstitutional" and claimed the Governor had "tarnished his post" by writing the letter.
