Nwako's classmates at Tiger Kloof such late associates as Motsamai Mpho, Edison Masisi, Washington Meswele and Quett Masire.
Throughout the 1950s, Nwako was among a group of young educated Gammangwato based progressives who called for political reform as well as the return of Seretse Khama from involuntary British exile.
[citation needed] Like Nwako, many members of this group, such as Monametsi Chiepe, Lenyeletse Seretse, and Gaolese and Kenneth Koma, belonged to the Malekantwa age-regiment (mophato).
In 1952-53, the Malekantwa activists, along with such older figures as Kgalemang Motsete and Leetile Raditladi, came together to form a political movement initially known as the Bamangwato National Congress.
[citation needed] The Congress stood as a new third force in Gammangwato politics between the rival camps of older traditionalists led by Tshekedi Khama and Keaboka Kgamane (pro-Seretse).
In January 1961, Nwako did join a BPP delegation that met the British Resident Commissioner, Peter Fawcus, to protest inequities in the electoral structures of the Legislative Council (Legco).
In 1994, he was succeeded as Tshwapong North MP by the then Vice President Festus Mogae, but continued to serve as Speaker until his retirement in 1999.
