For the CPI(M), a prestigious fight is on in Kollam where party's polit bureau member M A Baby is facing a grim challenge from RSP's N K Premachandran.
The battle in Kollam is keenly watched as the RSP's desertion of the LDF and joining the UDF came as a stunning development after declaration of elections.
The electoral fight in Palakkad has turned into high-stake affair with the entry of former union minister and SJD leader M P Veerendra Kumar into the fray.
The CPI(M) has fielded its sitting MP M B Rajesh to take on the socialist stalwart.
Alongwith national issues, local topics also figure prominently in the campaign.
