He has declared this position to lankacnews website with regard to talks between leaders of the UNP and the SLFP for a national government.
Weerawansa has claimed that if not for the disruptions by the president, the UPFA would have won more seats than the UNP at the general election.
He said the NFF was studying certain abnormalities in the results of Kandy, Colombo, Gampaha and Kegalle districts.
Anyhow, with 95 seats, the UPFA should remain a strong opposition, not a tail of the UNP, and if the government does something good, the opposition can extend support, he said.
Weerawansa polled more than 300,000 votes to top the UPFA list for Colombo, and five others of his party have also got elected.
