HARARE (Reuters) - Zimbabwe's ruling ZANU-PF and the opposition MDC on Wednesday called on their supporters to end political violence in the country.

In a joint statement, they urged "all our supporters and members and any organs and structures under the direction and control of our respective parties to stop and desist the perpetration of violence in any form".

The call came as a South African newspaper reported a draft agreement was being circulated aimed at ending Zimbabwe's political stalemate, which sparked much of the violence.

Under the plan, Zimbabwe's opposition leader Morgan Tsvangirai would run the country while President Robert Mugabe would become ceremonial president.

The Star newspaper said the draft document circulated among negotiators in Zimbabwe's power-sharing talks in South Africa also proposed an amnesty for Mugabe and others implicated in political crimes.

The paper said there was no agreement yet but quoted unnamed sources as saying the rival parties were receptive to the draft document.

Zimbabwean government and MDC officials were not immediately available for comment.

Mugabe's ruling ZANU-PF began power-sharing talks with Tsvangirai's Movement for Democratic Change (MDC) two weeks ago following Mugabe's re-election in June in a widely condemned poll boycotted by the opposition.

The Star said the draft settlement would be the basis for talks between Mugabe and Tsvangirai in Harare on Thursday.
