Chief Minister and CPI(M) veteran V S Achuthanandan has been the star-campaigner of the LDF.Congress leader and Defence Minister A K Antony was on the forefront of UDF camaign addressing scores of meetings for 11 days at a stretch.
National leaders, who came to address election meetings included Prime Minister Manmohan Singh, Congress president Sonia Gandhi, BJP leader L K Advani, AICC general secretary Rahul Gandhi and Chief Ministers Mawyawai and Narendra Modi.
In 2006, LDF won 98 seats and UDF 42, which was almost the reveral of 2001 tally, living upto to the state's reputation of alternating between the two coalitions every five years.
