The two candidates in the Zimbabwe presidential elections have spoken out after the Zimbabwe Electoral Commission announced on Friday that Emmerson Mnangagwa had won the historic vote.

The opposition leader, Nelson Chamisa, described the result as fraudulent and illegitimate at a press conference that was delayed when riot police dispersed waiting journalists.

Mnangagwa responded by saying that Chamisa had "a crucial role to play in Zimbabwe's present and future" and called on people to be "calm and peaceful".
