Shiv Sena leader Arvind Sawant said speculation about the Maharashtra alliance facing internal friction is wrong. "I too have certain friends in BJP. Political rivalry and ideology are different. Relations continue. We don't treat opposition as enemies," Mr Sawant said. "I-T and ED are harassing us and sometimes CBI too. The remedy is forming an alliance with BJP to close cases? Is it the right way to work? It means the ruling party is blackmailing."
