Zimbabwe's Mass Public Opinion Institute said it has suspended polling activities due to what it described as a deteriorating political situation that makes it impossible to come up with credible research results.
Director Eldred Masunungure said polls have been suspended until such time as conditions improve in Zimbabwean communities.
Recent reports said the institute issued poll results showing most Zimbabweans want President Robert Mugabe and Deputy Prime Minister Arthur Mutambara to step down.
Respondents added that they wanted Industry Minister Welshman Ncube, head of the smaller of two formations of the Movement for Democratic Change, to reunite his party with the larger MDC formation headed by Prime Minister Morgan Tsvangirai.
Masunungure told VOA Studio 7 reporter Sandra Nyaira that the findings emerged from focus groups his organization conducted in five of Zimbabwe's 10 provinces. The focus groups were designed to assess the performance of Zimbabwe's unity government.
MPOI Principal Researcher Stephen Ndoma said that when respondents were asked what they would tell political figures if given a chance to meet them, most said they would advise President Mugabe to retire now, and Mutambara to quit politics.
Mutambara refused to step down as head of the of the MDC wing now led by Ncube after being toppled from the party presidency by Ncube at the MDC formation's congress earlier this year. He alleged election irregularities and court action is still pending.
Some respondents said that if given the chance to meet Mr. Tsvangirai they would encourage him to lead the country's development efforts.
The MPOI says it aims to promote and strengthen democratic governance through research, publishing and facilitating discussion on issues of wide concern.
