Being out of power in their erstwhile bastion of West Bengal, these parties are now banking on states like Kerala and Tamil Nadu to at least maintain their presence in the Lok Sabha where the Left currently has 24 seats.
The Aam Aadmi Party (AAP) factor, a new phenomenon in the national polity, has also affected parties like CPI(M), CPI, RSP, CPI(ML) and Forward Bloc, with AAP succeeding in Delhi, taking on major parties like Congress and BJP to form government.
In protest against widespread violence against the entire opposition in West Bengal, the Left parties also expressed apprehension about a repeat of alleged Trinamool-sponsored violence and intimidation in the upcoming Lok Sabha polls. They moved the Centre as well as the Election Commission seeking their intervention to ensure free and fair elections.
They are also expecting a new combination after the general elections this year, saying the major parties would fall short of an absolute majority.
"It is now clear that the Congress-led UPA will not be in power after the upcoming parliamentary elections. While Congress will get only 110-120 seats, BJP can succeed on some more seats, but will not get more than 150 seats," veteran communist A B Bardhan recently said, adding that the Left parties were expecting a new combination to come to power.
