Kerala’s Congress party, which has been successful in bringing the RSP and a section of the Janata Dal (S) from the left camp into the UDF it is leading in recent past, has launched a bid to split the CPI(M)-led Opposition lDF further. The party’s Malayalam mouthpiece, Veekshanam daily, on Thursday asked the CPI to jump the left’s ‘sinking ship’ and join the ruling UDF in the context of the defeat of the lDF in the Aruvikkara Assembly by-election.
