Virtually rejecting Trinamool Congress' appeal to support a no-confidence motion to be brought by it, CPI(M) today said such a move would only help the government cover up all its "wrong" policies.

"A no-confidence motion (in Lok Sabha) will only help the government cover up all wrong measures it has taken and claim parliamentary mandate, as it has the numbers to defeat such a motion," CPI(M) General Secretary Prakash Karat said here.
