The PDP and BJP, who are still engaged in hectic negotiations to cobble up a majority, will meet Jammu and Kashmir Governor NN Vohra on Saturday to discuss government formation.
Earlier, none of the parties getting a clear majority in the recently-concluded J&K assembly elections left all major players checking each other out for a possible union.
Vohra had written to the BJP and PDP asking them to submit their proposals on forming the government. PDP won 28 seats compared to BJP's 25 in the polls.
According to sources, BJP is likely to submit a letter of support from the independent MLAs and inform the Governor that it has the largest post-poll alliance in the state. Along with its 25 MLAs, BJP has been claiming the support of six independents.
BJP leader Ram Madhav said on Friday that talks were being held with National Conference, whose leader Omar Abdullah resigned as Chief Minister, as well as PDP.
"PDP or NC (National Conference) should come forward to form a stable government... We are exploring the option of how best to form a good government so that we can deliver," Ram Madhav told NDTV.
BJP's best ever election results in Jammu and Kashmir have prompted their legislators to believe that their party should be the senior partner in a coalition government.
Jitendra Singh, who is currently serving as union minister, will be BJP's candidate for chief minister of the state, say party sources.
