Upon returning from Uganda, Anyona worked as an Assistant Secretary in the Office of the President between 1968 and 1970, as the Secretary General of the Kenya Red Cross Society in 1970 and as Nairobi Airport Manager then District Sales Manager for British Overseas Airways Corporation (BOAC) later renamed British Airways in Nairobi from 1970 to 1974.
He quickly established a reputation as a fearless firebrand and for thorough research before presenting issues in parliament, coming to be referred to as a 'one-man backbench' after parliament was neutered following the murder of JM Kariuki and the detention of then Deputy Speaker and Tinderet MP Jean Marie Seroney and Butere MP Martin Shikuku [1].
Anyona's political troubles began in 1977 when he was arrested within the precincts of parliament (an illegality in itself) for questioning the award of a tender for the supply of wagons to the then East African Railways and Harbours Corporation and detained without trial at Manyani Prison by then President Jomo Kenyatta.
However, it was later revealed by an Assistant Minister in the Office of the President, John Keen, that these allegations were nothing but government fabrications, aimed at silencing Anyona.
In a surprising move however, Anyona rejected FORD-Kenya's overtures, opting instead to launch his own political party Kenya Social Congress.
In the 1992 Multi-Party General Elections, he easily won the Kitutu Masaba Constituency parliamentary seat, becoming the only member of parliament from the KSC.
He served as the Chairman of the Public Investments Committee (PIC) of the national assembly for 1993/1994 and was re-elected as a member of parliament in 1997 for another 5-year term.
