MDMK leader Vaiko, charged with sedition for a speech warning of a 'bloodbath' in Tamil Nadu if anything happened to LTTE chief V Prabhakaran, on Friday said the case was 'politically motivated' and he was ready to face arrest.

"MDMK is second to none in protecting the country's unity and sovereignty and I don't need a certificate from Karunanidhi government on this matter," he told reporters at his residence where scores of his supporters had converged, apprehending his arrest. "I am not bothered about the arrest," Vaiko said.
