Imran was elected in November 2019 as a Member of Parliament succeeding his late brother, Ken Okoth.
Otieno completed his secondary education in 1995 at Kirangari High School. He worked in different private companies and was constituency manager of Kibra constituency from 2014 until 2019.
Since his election, Imran has done a number of development projects which have helped to shape the lives of Kibra residents. The projects have revolved around education, social amenities, infrastructure and health.
He has been applauded especially for his Kibra Scholarship Fund - which has helped many needy students from the slum to access education.
In 2020 Imran was ranked as the best performing MP in Nairobi in a poll done by research firm Infotrack. He trounced all the other 16 lawmakers to emerge the top performing legislator in the capital having held the position for less than a year. Okoth was followed by Westlands counterpart Tim Wanyonyi.
