President Uhuru Kenyatta's Jubilee Party and its allies (see note 1) secured the majority in both the 350-member National Assembly and the 68-member Senate. The National Super Alliance (Nasa, see note 2), led by former Prime Minister Raila Odinga, came second. During the election campaign, the Jubilee Party ran on the government record, citing major infrastructure projects and economic growth. Mr. Odinga criticized corruption in state institutions. Both leaders were candidates in the presidential elections, held in parallel with the parliamentary polls.

On 11 August, the Independent Electoral and Boundaries Commission (IEBC) declared Mr. Kenyatta's re-election as President, which sparked two days of protests. Mr. Odinga rejected the election results, and on 1 September, the Supreme Court invalidated the presidential election following a petition by Mr. Odinga. Fresh elections, initially scheduled for 17 October, were postponed to 26 October. On 10 October, Mr. Odinga withdrew from the race, citing the lack of reform to the election process. On 26 October, President Kenyatta won the repeat presidential elections.

Note 1:
The Jubilee Party was formed by 11 parties in September 2016. They included the National Alliance and the United Republican Party (which had formed the Jubilee Coalition for the 2013 elections) as well as other parties which supported Mr. Kenyatta’s candidacy in 2017: the Kenya African National Union (KANU), the Economic Freedom Party (EFP), Maendeleo Chap Chap Party (MCCP), the Party of National Unity (PNU) and the Democratic Party (DP). Together they took over 190 seats in the National Assembly and at least 37 seats in the Senate.

The Nasa took at least 127 seats in the National Assembly and 24 seats in the Senate.
