President Robert Mugabe was sworn in for a sixth term Sunday, just hours after officials announced that he had overwhelmingly won an election many countries have condemned as a sham. His main rival dismissed the inauguration and said the next step would be power-sharing talks. As dignitaries watched under a red-carpeted tent at the State House complex, Mugabe held a Bible and stood before a red-robed, white-wigged judge to swear to uphold his nation's laws, "so help me God." He then sat amid cheering supporters to sign documents. "The inauguration is meaningless," Morgan Tsvangirai, leader of the opposition Movement for Democratic Change, told Associated Press Television News. "The world has said so, Zimbabwe has said so. So it's an exercise in self-delusion."
