ABIDJAN (Reuters) - Ivory Coast's President Alassane Ouattara has named Daniel Kablan Duncan, a member of his allied PDCI party, as his new prime minister, Ouattara's office said on Wednesday.

The nomination of Duncan, who previously served as foreign minister, ensures that Ouattara sticks to a deal that saw the PDCI throw its weight behind Ouattara during a 2010 election run off in return for the prime minister's job.

Ouattara dissolved his government last week in a surprise move, citing the lack of solidarity within his coalition.
