Several petitions challenging the election of William Ruto as Kenya's president were rejected by the country's Supreme Court.

According to the BBC, the supreme court ruled that William Ruto, 55, who received 50.5% of the vote against rival Raila Odinga's 48.8%, was duly elected.

Following an alleged fraud in the election results, including the tampering of results, Raila Odinga and seven other candidates went before the court asking that the court declare the election null and void.

The court ruled that some of the eight petitions contesting the polls were based on false documents and "sensational facts," Chief Justice Martha Koome declared on behalf of the seven judges, according to the article.

"No credible evidence that the electronic voting transmission system had been tampered with by "a middle man" was presented," she said.

She also added that William Ruto met the constitutional threshold of garnering 50%+1 of votes cast.

William Ruto will be the country's fifth president when sworn in next week. Following the ruling, Mr Ruto's home area of the Rift Valley and parts of the Central region has seen massive celebrations by his supporters.

Meanwhile, the BBC reports that Kisumu, which is Mr Odinga's stronghold, seems quiet, with streets deserted and some businesses closed for the day.

President Uhuru Kenyatta, who was supporting Mr Odinga, is expected to address the country in the coming hours.
