Following a public gaffe by MPs at the opening of parliament, Zimbabwe's President Robert Mugabe has summoned MPs to a special session where he will correct the speech.

Mr Mugabe, 91, is expected to deliver the correct speech during Wednesday's extraordinary meeting.

On Tuesday, he accidentally read the same state-of-the-nation address he had already delivered on 25 August when he was heckled by opposition MPs.

The error has been blamed on a mix-up in the president's secretarial office.

The incident has prompted questions from members of the opposition over whether the nonagenarian president remains fit to lead the country.

The state broadcaster, which cancelled its live feed of Tuesday's speech, called on MPs to show up for an extraordinary session of parliament on Wednesday, says the BBC's Brian Hungwe in the capital Harare.
