New Delhi (PTI): Mounting pressure against a strategic tie-up with the US, the CPI(M) is planning to demand nullification of the Defence Framework Agreement with it and ask both Congress and BJP not to become part of America's global military plans.

The major Left party would debate this issue in its upcoming Congress in Coimbatore starting from March 29.

On the political front, it would also hold discussions on how to shape a 'Third Alternative' on the basis of commonly agreed policies, while trying to "isolate" the "communal" forces led by the BJP.

The six-day 19th Congress would be inaugurated by General Secretary Prakash Karat in the presence of his counterparts from all the Left parties as well as a large number of foreign fraternal delegates. The meet would culminate with a massive public rally on April three.

Maintaining that CPI(M) would ensure that the nuclear deal "does not go forward", Karat has said "there is a long struggle ahead. The defence framework agreement should be nullified."

"What has to be accomplished is the disentanglement from a strategic tie-up with the US. This requires the mobilisation of all patriotic and anti-imperialist forces in the country and a sustained movement to force both the Congress and the BJP to desist from pursuing such a course," he said in an article in the forthcoming issue of CPI(M) organ 'People's Democracy'.
