The Communist Party of India is leading the Left's fight back to remain alive in Assam politics after being wiped out in the last Assembly polls for the first time since independence.

The CPI, a senior partner in the state compared to the Communist Party of India-Marxist, is leading the charge, trying to win at least three seats while the latter is giving a tough fight in two constituencies.

Both parties worked tirelessly in their pockets to be in a strong position once again. In Nazira constituency, the regional headquarters of the Oil and Natural Gas Commission, former Rajya Sabha member Dhrupad Borgohain is giving a tough time to unseat Dr Hemopraba Saikia from the constituency, held by the Saikia family since 1963.

''This time nobody can stop us,'' said Borgohain, buoyed by the support from the Asom Gana Parishad after a long gap.

Already, the CPM has been bringing in West Bengal leaders like Hannan Mollah for campaigning, but they are a little behind the CPI, which has better mass base.

The main opposition party, AGP, have thrown their weight behind the left parties to ensure that the Congress candidates are kept at bay.
