HARARE -- Zimbabwe's main opposition party, the MDC Alliance, says it is ready with its Constitutional Court challenge of the July 30 presidential election result which will be lodged with the courts before expiry of the stipulated seven-day deadline on Friday, the party's lawyers say.

President Emmerson Mnangagwa of Zanu PF was proclaimed winner of the general election with 50.8 per cent of the votes against the MDC Alliance's Nelson Chamisa who polled 44.3 per cent.

Chamisa, however, declared the result as pronounced by the Zimbabwe Electoral Commission (ZEC) last Friday as fraudulent, arguing he had won the election. Zimbabwe's Constitution gives a seven-day window to any aggrieved candidate in an election to challenge the result.

Chamisa's lawyer, Advocate Thabani Mpofu, told journalists here Wednesday that the court challenge was ready and would be lodged with the highest court in the land before the deadline lapses.

Results have now been announced and my client's view is that those results reflect a total negation of the will of the people, Mpofu said, refusing to disclose the date when the party will lodge the court application.

Taking into account that Zimbabweans are entitled to a proper election, the results announced, that declaration made by ZEC is going to be challenged. The relevant challenge has already been prepared.

Mpofu said the anti-rigging mechanism which the MDC Alliance claimed to have put in place before the polls had assisted them in establishing how the ZEC allegedly stole the election.

The evidence that we have amassed is so clear, it is so convincing, we are happy with it, Mpofu said. That evidence derives from source documents, that evidence derives from ZEC's own figures which in our view are grossly made up and mathematically fail to tally.

He said their legal team also had a secret weapon which we are going to unleash through this court challenge without giving any hint as to what this is.
