SLFP General Secretary Dayasiri Jayasekera said the party's final decision on the Presidential election would be announced tomorrow.
Although the party's decision was expected to be announced following the ruling of the court case involving SLPP candidate Gotabahaya Rajapaksa last Friday, the party kept delaying the move.
Although the SLFP has held a number of meetings since the outcome of the case, no final decision has been made thus far.
Itis reported that the SLFP is more inclined to announce support for SLPP candidate Gotabhaya Rajapaksa.
Opposition Leader Mahinda Rajapaksa and his brother, Gotabhaya Rajapaksa, have held several discussions with Sirisena on working together at the next Presidential election.
