The wife of Zimbabwe’s Prime Minister Morgan Tsvangirai, who was killed in a car crash is expected to be buried on Wednesday, a senior MDC and government official said on Sunday.

Tsvangirai was flown to neighboring Botswana on Saturday to recover from the accident and to undergo another medical check-up, but is expected to return to Harare late on Monday, the official, who asked not to be named, told Reuters.

“The arrangement is that Mrs. Tsvangirai will be buried on Wednesday in her rural home of Buhera,” he said. A procession commemorating her would be held in Harare on Tuesday.

Tsvangirai, who left hospital in the capital on Saturday, has suffered head and neck wounds, but is in stable condition, other officials said.

Police have launched an investigation into the accident, which took place on Friday on a potholed road south of Harare.

Tsvangirai’s MDC said they would conduct their own probe to see whether foul play was involved. The party said the crash could have been avoided if proper security had been in place.
