Zimbabwean police has banned a planned weekend opposition campaign rally over lack of toilets and unsuitable roads to the venue as the country gears for general elections next month.

Political temperatures are rising in the run-up to what is expected to be a tense vote on August 23. The ruling Zanu PF party is facing its biggest challenge from the largest opposition group, the Citizens Coalition for Change (CCC) of 45-year-old Nelson Chamisa.

The rally, scheduled for Sunday in Bindura town, 90 kilometres northeast of the capital, Harare, is the fourth CCC meeting to be banned countrywide within a week.

Bushy venue

A police letter stopping the rally said the venue was a "bushy" piece of land "without serviceable roads, water and sewer facilities".

It said there was a "high risk of threat to the spread" of communicable diseases.

The venue poses "a high-risk security threat" to the rally-goers, it added, saying if there was any public disorder, the police and emergency workers would struggle to access the venue "due to unavailability of an official road network".

"Our mandate to protect life and property and to maintain law and order will be compromised," said the police, adding the opposition failed to give sufficient notice of the meeting, which is seven days in advance, as stipulated by the law.

Launch manifest

The gathering, where the CCC was going to formally launch its election manifest, was much anticipated.

President Emmerson Mnangagwa, 80, who replaced Robert Mugabe in 2017 after a military-led coup, is seeking re-election.

The southern Africa country is battling high cost of living, poverty and high unemployment.

Tendai Biti, a senior CCC lawmaker, tweeted that the continuous banning of their political events reduces "this election to an absolute charade".
