Former president Uhuru Kenyatta eulogised Biwott as a "patriot and diligent leader, who spent decades building schools and hospitals and spearheading every other kind of development including marketing Kenya abroad".

After finishing secondary school in 1959, Biwott began working at the Department of Information in Eldoret, after which he published the Kalenjin monthly newsletter with Kendagor Bett.

He attended the University of Melbourne, Australia, from 1962 to 1964, where he earned a Bachelor of Arts degree in Economics and Political Science, as well as a Diploma in Public Administration.

In the Parliamentary elections held on 27 December 2007, running on a KANU ticket, he lost his seat to Jackson Kiptanui Arap Kamai of the Orange Democratic Party (ODM).

[citation needed] Having completed his master's degree in Australia in 1968, Nicholas Biwott returned to public service in the Ministry of Agriculture, GOK, Personal Assistant to Minister Bruce MacKenzie (1968–70).

Following the 1974 election, Nicholas Biwott was recalled to the Ministry of Home Affairs as Under Secretary (1974–78) to Minister Daniel arap Moi, Kenya's vice-president.

With the ageing President Kenyatta unable to fulfil all the functions of the presidency, Moi took a leading role in the East African region with the result that Nicholas Biwott spent much of the next four years dealing with the Organisation of African Unity, the Commonwealth, the 'non-aligned' states and promoting the 'good neighbourliness' policy with states bordering Kenya.

As a teenager in the late 1950s, Biwott worked alongside his father who had established a successful fruit and vegetable business in Eldoret.

The young Biwott also borrowed small amounts of money from a local bank with which to expand his own business sideline selling meat products and eggs.

Within a few years, Nicholas Biwott was able to invest in farms and businesses, taking advantage of the post-independence banking policies at the time by which Kenyans were granted loans on favourable terms.

[12] His supporters maintain that the allegations, none of which have ever been proved, arose from the campaign at the time to introduce multi-party democracy in Kenya coupled with Biwott's association with President Moi.

The most serious of the allegations surrounding Biwott is the fact of his being named as a person of interest by Scotland Yard detective John Troon in his final report on the 1990 murder of Kenya's Foreign Affairs Minister Robert Ouko.

Troon's basis for naming Biwott in his final report on the Ouko murder was based on statements by two witnesses: Marianne Brinner-Mattern and Dominico Airgahi.

The contract was terminated before Ouko’s death because of the company’s failure to raise bilateral funding and to conduct an agreed-upon feasibility study.

Schaffer who were nominated and paid for by the US Embassy and USAID under the leadership of Dalmas Otieno, the then Minister of Industry since assuming the ministry from Dr Robert Ouko.

Another reason given for the refusal by the Metropolitan Police to review the case was that the Kenyan Parliamentary Select Committee (PSC) was investigating the death of Dr Robert Ouko and that it was 'open to Mr Biwott to make any representations he wishes to that Inquiry'.

Six members – Paul Muite, Mirugi Kariuki, Dr Abdulahi Ali, Njoki S. Ndung’u and Otieno Kajwang – resigned during its hearings.

In 2000, High Court Judge Alnashir Visram awarded Mr Biwott a record damages of Sh30 million, the biggest settlement in a defamation case in Kenya.

[19] Biwott was awarded the Sh30 million damages after he sued a British journalist, Chester Stern, and others for linking him to the Ouko murder in a book entitled 'Dr Iain West's Casebook'.

Bookpoint and Bookstop, popular Nairobi bookshops, also paid Biwott 10 million in damages for stocking copies of the book Dr Ian West's Casebook.

In March of 2002, Kalamaka Ltd., the publisher of the People Daily newspaper, was found guilty of the “unmitigated and defenceless character assassination” of Mr. Biwott.

Gicheru had sued Andrew Morton, author of a biography on the president "Moi -The making of an African statesman" and the publisher Michael O Mara Books.
