Michel Martelly faces a mammoth task after he is sworn as Haiti’s new president on Saturday, inheriting a shattered Caribbean nation.

Haiti won plaudits for holding a calm and relatively peaceful presidential run-off on Monday as partial results suggested Michel Martelly could win.

The US has urged Haiti’s former president to postpone his planned return to the country until after Sunday’s vital presidential run-off.

A candidate in Haiti’s presidential run-off said on Thursday she hoped popular former president Jean-Bertrand Aristide would delay his planned return.
