A crucial meeting of the CPI(M) Politburo will take place in Kolkata on January 15 and 16.
Apart from reviewing the political situation in Kerala and West Bengal, the meeting has been called to firm up the party's stand on the spectrum issue as well as inflation ahead of the budget session of Parliament next month.
The CPI(M) is in power in both the states, which will go to polls this year.
Though the party's demand for a joint parliamentary probe into the spectrum issue stands, it will discuss with the fellow Left and likeminded parties before firming up the strategy to be adopted to press the demand, party sources said.
The Left has reservations about the House sessions going waste, especially the upcoming budget session, but party leaders feel that the Congress is deliberately "brazening it out" on the spectrum issue to 'cover up' the issue.
Party sources feel telecom minister Kapil Sibal rubbishing the Comptroller and Auditor General report highlights the hidden agenda.
The party sees the systematic cover-up in the pattern of moving from the Congress's initial emphasis on a Public Accounts Committee with investigative agencies attached to it probing the spectrum scam to brazening it up a few days later. The Politburo will discuss party's response to the "government's inability" to address the rising prices.
The meet will also discuss the political situation in Kerala and West Bengal, where the party is faced with an uphill task of staying in power.
The Centre is supporting its ally, the Trinamool Congress, whose "Naxal links" are out in the open, say party sources. The party also feels there is a slight improvement in its prospects of late, going by the support the party rallies have elicited.
