Results from Zimbabwe’s presidential election, in which President Robert Mugabe is the only candidate, have been delayed but the outcome should be announced soon, electoral officials said.

Earlier, government sources said they expected Mugabe to be inaugurated on Sunday in time to attend an African Union (AU) summit in Egypt on Monday. It was not clear how much the delay, caused by the wait for results from rural areas, would hold up the swearing-in.

The election was widely condemned around the world after opposition leader Morgan Tsvangirai withdrew a week ago, saying almost 90 of his supporters had been killed in government-backed violence.
