"Congratulations to President-Elect William Ruto of Kenya... Looking forward to continue our excellent cooperation on regional affairs and deepening EU-Kenya relations," he said on social media.
Kenya's national electoral bureau declared the 55-year-old the country's fifth president on Monday, almost a week after the August 9 polls.
Michel called the vote peaceful and urged Ruto's rivals to use "existing resolution mechanisms," in a hint to Raila Odinga, President Uhuru Kenyatta’s preferred successor, who refused to concede his defeat and vowed to contest results in the top court.
