Osman resigned early so Sharmarkee could preside over independence day

Evidence

Finally Osman, rather than wait until the last official moment, magnanimously offered to vacate the post so that the new president would have the honor to preside over the July 1 independence commemorations. He informed Sharmarkee and the Speaker of the parliament about his intentions, and on June 30 he resigned and the new head of state was sworn in immediately. — Abdi Ismail Samatar, Africa’s First Democrats, 948
