Zimbabwe opposition leader Morgan Tsvangirai has been sworn in as prime minister in a unity government with his long-time rival President Robert Mugabe.
Mr Tsvangirai took the oath of office in a ceremony before an invitation-only crowd at Mr Mugabe's official State House compound.
The opposition leader won a first round presidential poll against Mr Mugabe last year but boycotted a subsequent run-off over electoral violence.
Implementation of the power-sharing deal only came after increased pressure from southern African countries, fearing a total meltdown in once-prosperous Zimbabwe.
Mr Tsvangirai is a former trade union leader known for fiery speeches, but his leadership skills in government remain untested.
Zimbabweans hope the new government will bring policies to revive a country suffering hyper-inflation, unemployment above 90%, food shortages and a cholera epidemic that has killed nearly 3,500 people.
