``We will also open a dialogue with those who dissociate from the TDP and come out into the open,'' the CPI(M) State secretary B.V. Raghavulu told reporters here.

``There is no political basis to continue the alliance with the TDP since it has dealt a blow to secular forces by sailing with the BJP,'' he said, adding the the CPM had decided to forge an alliance with ultra-Left groups like Praja Pandha and Janashakti in the State.

The decision to break the 15-year-old bond with the TDP was taken at the party's two-day State secretariat meeting which concluded here on April 8. The CPI, has already severed links with the ruling party on similar grounds.The CPI(M) leader said his party would strive to strengthen an alternative Left, democraticand secular force to take on the BJP, Congress and TDP in the State.

Making a scathing attack on TDP supremo and Andhra Pradesh Chief Minister N. Chandrababu Naidu for ``sacrificing principles to have an unprincipled understanding with the BJP,'' he said that his party, along with the CPI, would intensify the struggle against ``anti-people'' policies of the TDP Government.

Moves were on to convene a public meeting here to explain the United Front's position on secularism and the TDP's volte-face on the issue, Raghavulu said.Efforts would also be made to strengthen Left unity and explain to people the ``dangers of the hidden communal agenda of the BJP,'' he said.He denied the allegation that his party had been soft towards the Telugu Desam Party despite serious political differences.
