Gideon Sitelu Konchellah, the former Kilgoris MP and Minister for Immigration, is dead. He died at 4 am on June 12 after suffering a cardiac arrest while being treated at a Nairobi hospital. He was 73.

Education Principal Secretary John Ololtuaa broke the news on Saturday. He told journalists that Konchellah hadn't been well since November 2025, when he was treated at Nairobi Hospital. He was readmitted on May 30 with an infection. The cardiac arrest struck on June 12.

Konchellah's body is at Lee Funeral Home. His death has triggered a flood of tributes from across the country, especially in Narok County, where he remained a political heavyweight long after leaving elective office. President William Ruto, Narok Governor Patrick Ole Ntutu, County MP Rebecca Tonkei, and Kilgoris MP Julius Sunkuli all sent condolences.

"I've sadly learnt of the death of Honourable Gideon Konchela, former MP for Kilgoris constituency," Sunkuli said. "The late Konchela was both my successor as well as my predecessor."

Konchellah was MP for Kilgoris from 2003 to 2022 — one of the longest-serving legislators in the constituency's history. He navigated Kenya's shifting political landscape under the Party of National Unity (PNU), the United Republican Party (URP), and later Jubilee Party, all while keeping a strong grassroots base.

Born and raised in the larger Trans Mara region, he rose to become one of the most recognisable political figures in the Maasai community. His 2002 election win launched a career that made him a key player in both local and national politics.

His biggest national moment came when former President Mwai Kibaki appointed him Minister for Immigration and Registration of Persons in 2006. He held the post until 2007. During that time, he oversaw immigration reforms and played a big role in passing the Refugee Act of 2006, which strengthened Kenya's legal framework for managing refugees.

As MP, Konchellah pushed development projects in Kilgoris and the wider Trans Mara region — schools, roads, water, security, and public services. Narok County Assembly Speaker Davis Dikirr, who worked closely with him, said Konchellah spearheaded projects that transformed communities and expanded access to services in one of the county's historically marginalised areas.

"His influence extended far beyond constituency politics," Dikirr said. "For many years, Konchellah was considered one of the key power brokers in Narok County, often playing a central role in regional political alignments and leadership negotiations."

Konchellah shared the political stage with veteran politician Julius Sunkuli and former Narok Governor Samuel Tunai. The three shaped the county's political direction over decades. Konchellah and Sunkuli had a relationship stretching back years, often finding themselves on opposite sides of political contests as alliances shifted.

His death marks the end of a political career that spanned more than two decades and helped shape the South Rift region's political landscape.
