Grace Mugabe returns home

President Robert Mugabe's wife Grace who is said to be battling colon cancer quietly flew back into the country last weekend from the Far East where she had gone for medical treatment.

Sources close to the First Family said Grace was in the country.

A picture showing a frail-looking Grace Mugabe has gone viral on social media.

In the picture, a seemingly "wasted" Grace appears to be inside state house, standing next to an unidentified woman.

In the same picture, President Robert Mugabe is seen shaking hands with a man wearing a shirt with South African national flag colours.

This comes as the first lady's health remains a mystery, with Zimbabwean media quoting close family sources as saying she is suffering from colon cancer and is in Singapore for treatment.

"The first lady is suffering from colon cancer. She had an operation while on holiday in Singapore and has gone back there for treatment. About 30cm was removed, but now she is in a bad state. That is why she disappeared from the public spotlight," a relative was quoted as saying by the Zimbabwe Independent.

Last week a ruling Zanu-PF politburo member, Oppah Muchinguri confirmed that Mugabe's wife was not well and was seeking treatment outside the country.

Grace has not made a public appearance since 8 March, when she officiated during commemorations to mark the International Women's Day.

The first lady was forced to remain in Singapore in January after the first family's annual holiday, with Mugabe telling supporters on his arrival back home that the first lady had undergone appendix surgery.

Grace later came back home and said she was "fit" to drive the ruling party's women's league agenda.

She also revealed that the latest surgery was the third operation she'd had, after having her tonsils removed in 1986 and gall bladder surgery in 1996.

Grace dominated Zimbabwe's political space towards the end of last year when she was nominated to lead the Zanu-PF Women's League.
