Speculation is raging over a road crash that killed the wife of Zimbabwe's recently-installed prime minister Morgan Tsvangirai.

The MDC leader was travelling south of Harare when his convoy was apparently hit by a lorry.

Mr Tsvangirai, 56, and an aide escaped with minor injuries, but his wife Susan died.

There was immediate speculation the crash may have been an assasination bid.

Mr Tsvangirai only became premier last month after reaching a power-sharing deal with his bitter rival Robert Mugabe, who remains president.

The agreement came after almost a year of political stalemate which saw the country plunge into even deeper economic turmoil.

Zimbabwe has also been hit by a devastating outbreak of cholera which has claimed thousands of lives.

Mr Tsvangirai was highly critical of the handling of the crises in his maiden speech to parliament as PM on Wednesday.

We are deeply saddened to hear news of Susan Tsvangirai's death and we offer our condolences.

Foreign Office

Mr Mugabe has visited Mr Tsvangirai in hospital in Harare in the hope of quashing rumours he was involved in the accident.

But the rumours persist despite the driver of the lorry having said he was asleep at the wheel.

A Downing Street spokesman said: "The Prime Minister has sent his condolences to Morgan Tsvangirai."

A Foreign Office spokeswoman added it was "monitoring the situation closely".

"We are deeply saddened to hear news of Susan Tsvangirai's death and we offer our condolences," she said.

Mr Tsvangirai and his wife, who were married in 1978, had six children.

She preferred to stay out of the limelight but appeared by his side when he was charged with treason for opposing Mr Mugabe and put on trial.
