After successfully leading the agitation on Lokpal Bill, Gandhian Anna Hazare on Saturday struck a note of caution, expressing apprehension over parliamentarians' readiness to pass a strong anti-corruption legislation and asked his supporters to be prepared for a "bigger battle". Addressing the media, the 73-year-old social activist said "power-hungry" politicians will not easily accept any bill having stringent provisions against corruption or "shed" the power they enjoy. "But on this issue, people will get together," he said adding, MPs and MLAs were being elected to serve the people and not to be their masters. "But they (elected representatives) have forgotten this."
