LUSAKA, Aug 19 (Reuters) - Zambian opposition leader Brian Mundubile said on Wednesday that he would challenge this week's presidential election result in court, alleging vote fraud in the contest that handed President Hakainde Hichilema a second term in office.
"Our campaign has documented serious irregularities, inconsistencies and circumstances surrounding the conduct, counting, transmission and declaration of results", Mundubile said in a statement.
An election strategist for Hichilema declined immediate comment but said he would comment later.
The election commission declared Hichilema the winner with about 60% of valid votes in the early hours of Tuesday morning, compared with 38% for Mundubile.
After a relatively quiet run-up to the August 13 election in the mineral-rich Southern African nation of 22 million people, tensions escalated rapidly after the polls closed.
The authorities arrested 11 people including leading opposition figures in a raid that involved an exchange of gunfire, while Mundubile was present.
The electoral commission also suspended vote-counting for hours due to reports of violence against polling staff and the theft of ballot papers.
