``Though we (CPI-M) are a small political party, we have greater political responsibility in the present national situation,'' Basu said, addressing the 32nd anniversary celebrations of CPI(M) daily Ganashakti here.

Despite the Congress leadership's declared stand of not initiating any move to destabilise the Vajpayee Government, the octogenarian West Bengal Chief Minister maintained his party's issue-based support offer to the Congress ``to form a Government at the Centre as the lone alternative and intermediate step in the present political situation.''

``It is my firm conviction that there is no alternative to what we have offered to the Congress, since the Vajpayee Government will crumble as a fallout of internal feudsamong coalition partners,'' Basu asserted.

Basu, who came down heavily on the BJP-led coalition for bringing the nation ``to the brink of collapse'' with its ``disastrous'' policies, alleged that ``this uncivilised and barbaric Government at the Centre is out to dismember India.''
