The plenum would mainly deliberate organisational matters in view of the decisions and resolutions of the 20th party congress at Kozhikode in April 2012, a CPI(M) statement said here today.
Under the CPI(M)'s scheme of things, a plenum is held rather rarely between state conferences every three years.
The meet, to be attended by central leaders, state committee members and selected delegates, would conclude with a rally, it added.
