BSP supremo Mayawati has already announced that the issue of continuing support to the UPA government would be discussed after the party's 'maha rally' on October 9, the sources said.
They said a final decision on continuing outside support to the UPA would be taken at the party's National Executive Meeting next month where "anti-people" decisions of the Centre would be discussed.
BSP has 21 members in the Lok Sabha, two more than Trinamool Congress.
BSP's announcement came as a huge relief to a beleaguered UPA a day after Mamata Banerjee decided to withdraw TMC ministers from the Union government and the party's support to the Congress-led coalition.
