Paris - French President Nicolas Sarkozy on Monday joined the growing international chorus of voices urging Zimbabwe's controversial president, Robert Mugabe, to leave office.

"The president of Zimbabwe, Robert Mugabe, must go," Sarkozy said during a speech commemorating the 60th anniversary of the Universal Declaration of Human Rights, which is on Wednesday.

London  - Citing the cholera epidemic in Zimbabwe as yet another sign of ruin in Zimbabwe, a top ranking official in Britain's Anglican Church Sunday added his voice to the calls for President Robert Mugabe to be forced out of office and put on trial in The Hague.

The call by John Sentamu, the Archbishop of York and second only to the Archbishop of Canterbury in the church hierarchy, followed similar urgings from South African Bishop Desmond Tutu, who Friday called for the international community to intervene.

HARARE, Zimbabwe, Dec. 5  -- The Zimbabwean government has asked for British help in dealing with a cholera epidemic that has claimed hundreds of lives.

British Prime Minister Gordon Brown, often blamed by President Robert Mugabe for Zimbabwe's economic free fall, responded by promising at least $15 million in assistance, The Times of London reported.

At least 570 people have died of cholera and 13,000 have become infected in recent weeks. Some of the sick have crossed into South Africa seeking medical care, the newspaper said.

The disease, spread by ingestion of contaminated food or water, can be prevented by proper sanitation.

Harare - Zimbabwe's opposition Movement for Democratic Change (MDC) on Friday said it would not participate in a government of national unity with President Robert Mugabe unless he met the party's conditions for sharing power.

Addressing journalists in Harare after a key party meeting, MDC vice president Thokozani Khupe said the MDC would not govern together with Mugabe unless the constitution was first amended to enshrine party leader Morgan Tsvangirai's powers as prime minister.

Harare/Johannesburg  - Zimbabwe's President Robert Mugabe has been asked by his ZANU(PF) party on Wednesday to form a government of national unity even if the opposition does not want to be involved.

Addressing journalists in the Zimbabwean capital Harare, ZANU(PF) spokesman Ephraim Masawi said "the Zanu politburo unanimously agreed that President Mugabe form a government of national unity like yesterday. This is in conformity with the SADC (Southern African Development Community) resolution reached over the weekend."

This latest development is likely to further strain relations between ZANU(PF) and the opposition Movement for Democratic Change (MDC).

Johannesburg  - The suffering of Zimbabweans looked set to continue for some time to come Sunday after a summit of Southern African leaders tried but failed to breathe life into Harare's floundering power-sharing agreement.

After more than nine hours of talks among leaders of the 15-nation Southern African Development Community (SADC), Zimbabwean President Robert Mugabe and prime minister-designate Morgan Tsvangirai remained far apart on how to divide power.
