Kenya's Supreme Court has annulled the result of the country's recent presidential election.

Citing irregularities, the Supreme Court said a new poll should be held within 60 days.

The election commission had declared incumbent President Uhuru Kenyatta the winner of last month's election.

Chief Justice David Maraga said the 8 August election had not been "conducted in accordance with the constitution" and declared it "invalid, null and void".

He said the verdict was backed by four of the six Supreme Court judges.
