The JD(U) leader said these parties put together have almost equal number of MPs, what the BJP has and hence the strategy in future is to keep a separate secular non-Congress identity for this block both in Parliament and outside.
"There is a need for these parties to take a common ideological position on some issues as so far it is BJP, which is mainly seen as opposing the Congress on policies," he said.
On February 5 when Parliament meets, the leaders of these parties will come together and try to formulate a common position on many issues.
"There is the issue of Centre State relations.While the Centre realises taxes from states as well, most the schemes of public welfare are decided by the Centre be it MGNREGA or JNURRM. 50% of schemes should be decided by states for which central funding goes as the central fund is also from taxes collected from states," he said.
Tyagi's remarks came a day after AIADMK chief J Jayalalitha clinched a deal with CPI for Lok Sabha polls.
JD(U), AIADMK, BJD, AGP, SP, JDS and JVM (P) had also attended the Convention Against Communalism on October 30.
JD(U) President Sharad Yadav has expressed confidence of non-Congress non-BJP parties coming together despite internal contradictions in some states citing examples from past and asserting that such a possibility exist for future as well.
JD(U), which walked out NDA in June last year, has made it clear that it will maintain equidistance from both Congress and BJP.
Tyagi also cited the case of inauguration of the extended branch of Aligarh Muslim University in Kishanganj in Bihar on January 30 by UPA Chairperson Sonia Gandhi as another example of Centre ignoring states alleging that Bihar Chief Minister Nitish Kumar got an invitation for it only one day before the function despite the state giving land.
Giving an inkling of their strategy in Parliament, he said, "We have seen reports that the Finance Minister and the Rail Minister could announce some populist schemes to help Congress in elections.We will oppose it tooth and nail.
"They should confine their work to present vote on account for which this session has been called.If they go beyond, then this group of secular parties will oppose the government on the floor of the House," Tyagi said.
