In the capital city constituency, the CPI appears to have zeroed in on Bennet Abraham, a practising anaesthetist with a leading private hospital.
But his name too has come under fire from a section of the CPI.
In the 2009 Lok Sabha polls, the Left opted for just one non-party candidate, who lost heavily in the Ponnani constituency.
The CPI-M in the past has unsuccessfully fielded film personalities like director Lenin Rajendran and also late actor Murali.
