Supreme Court of Kenya confirms William Ruto as winner of nation's presidential election

The Supreme Court of Kenya on Monday confirmed William Ruto as the victor in the nation's Aug. 9 presidential election. 

The election was close, with Ruto defeating opponent Raila Odinga by 50.5%-48.8%, BBC reports.

There were accusations of vote tampering during the election, with multiple petitions challenging the results.

The petitions were all dismissed by the court. 

"No credible evidence that the electronic voting transmission system had been tampered with by a supposed 'middle man' was presented," Chief Justice Martha Koome said in the unanimous decision reached by the seven judges. 

After Ruto's victory was announced, he promised in a speech that he would work to unite the country. 

"We are not enemies, we are Kenyans," Ruto said. "Let us unite to make Kenya a nation of which everyone shall be proud to call home."

Ruto was not backed by outgoing President Uhuru Kenyatta, who openly supported Odinga, according to BBC. Kenyatta said his intention is to have a smooth "transition to the next administration."

Ruto is set to be sworn in as Kenya's fifth president next week.
