All the four Left parties on Wednesday gave letters of support for a Congress-led government at the Centre, as Congress President Sonia Gandhi held a meeting with CPI(M) General Secretary Harkishan Singh Surjeet to seek their approval for the candidature of Manmohan Singh for Prime Ministership.

Fresh letters were required as those given earlier by the CPI, CPI(M) and Forward Bloc had become infructuous since they spoke of giving support to a Sonia Gandhi-led government, a possibility now ruled out with the Congress President turning down the proposal.
While letters, addressed to the President and carrying the list of MPs each party had, were given to the Congress, the RSP leaders gave their letter to President APJ Abdul Kalam straight, Left sources said.
