"All the signatures are genuine," Chaudhary, RJD MLA from Parbatta in Khagaria district, said. "I and other leaders once again appeal to colleagues to discharge their constitutional duty as legislators and quit the RJD," he said.
Chaudhary, at whose residence the dissident MLAs met yesterday to make their decision public, claimed that many of them returned under "pressure".
