The US and UK have expressed concern after official results from Zimbabwe’s elections gave President Robert Mugabe a seventh term in office amid claims of electoral fraud. US Secretary of State John Kerry said the results did not “represent a credible expression of the people”. But the regional power South Africa has congratulated Mugabe on his victory. Mugabe, 89, won 61% of the vote, against Prime Minister Morgan Tsvangirai’s 34%. Tsvangirai, though, rejected the vote for parliament and president as fraudulent and vowed to take legal action, reports the BBC. He said his Movement for Democratic Change (MDC) would no longer work with Mugabe’s Zanu-PF party and boycott government institutions. The two parties have been in a coalition since 2009, after the last election sparked widespread violence.
