At 27 years old, Affey was one of the youngest politicians in Kenya's history
to be elected to Parliament, representing Wajir South constituency on a KANU Party ticket. He served a stint in the Ministry of Foreign Affairs as
Deputy Minister from 1997 to 2002. In 2002, Affey tried to defend his nominated parliamentary seat on a KANU ticket, but lost in the primaries. In July 2003, President Mwai Kibaki appointed him as '''Kenya's Ambassador to Somalia
, a position he held until May 2007 before he resigned and served as a nominated member of parliament for ODM-Kenya until 2013.
He then vied for the Senator of Wajir County on a WIPER Party ticket which he lost. He was thereafter appointed as the
IGAD's Special Envoy to Somalia''' and served for three years. In 2016, Affey was appointed by the High Commissioner for Refugees,
Filippo Grandi, to become
the UNHCR Special Envoy to the Somalia Refugee situation, one of the most protracted refugee situations in the world. During his mandate, he actively participated in the development and
implementation of the IGAD Nairobi Declaration for Refugees, aiming to deliver durable solutions for more than 900,000 Somali refugees as well as over a million displaced persons within Somalia. In 2018, he was appointed as
the first UNHCR Special Envoy for the Horn of Africa, covering the eight
IGAD countries. His mandate consists mainly in political advocacy to find durable solutions for the displaced population in the Horn of Africa, and is also extended to parliamentary engagement, resource mobilization and stakeholder engagement (including the private sector, diaspora and celebrities). The UNHCR Special Envoy for the Horn of Africa is currently based in Nairobi but often travels in the region and worldwide to perform his mandate. ==References==
