Geingob, 82, allegedly died after battle with cancer, a presidential release said on Sunday.
“It is with utmost sadness and regret that I inform you that our beloved Dr. Hage G. Geingob, the President of the Republic of Namibia has passed on today,” a statement signed off by the acting president, Nangolo Mbumba, said.
Mr Geingob had travelled to the US for “treatment therapy” for cancerous cells but died late Saturday, days after returning to Namibia to continue receiving treatment.
“His medical team, as I informed the nation only yesterday, has been trying its utmost best to ensure that our President recovers. Regrettably, notwithstanding the team’s spirited effort to save his life, sadly, fellow Namibians, President Geingob passed on,” Mr Mbumba said.
He described the president’s passing as the loss of a “distinguished servant of the people, a liberation struggle icon, the chief architect of our constitution and the pillar of the Namibian house.”
He urged Namibians to remain calm and collected while the government attends to all necessary state arrangements, preparations and other protocols
Hage Geingob Reigned 12 as Prime Minister Before Becoming President
Hage Geingob served for 12 years as prime minister before becoming president. He was said to have had a history of health problems that preceded his election as Namibia’s third president in 2014.
In 2013, he underwent brain surgery, and the following year he revealed that he had survived prostate cancer.
