Members of the Mau Mau War Veterans Association have been gathering in Kenya's capital Nairobi to hear the British government announce a compensation deal relating to torture in the former colony.
The simultaneous statement by the Foreign Secretary William Hague and British High Commissioner is expected to include details of a multi-million pound settlement and a formal apology. It will be addressed to victims of colonial-era torture.
The Foreign Office had attempted to stop the case and claimed the actions were brought outside the legal time limit and claimed there were "irredeemable difficulties" in relation to the availability of witnesses and documents.
It did not, however, dispute they suffered "torture and other ill-treatment at the hands of the colonial administration".
Lawyers for Wambugu Wa Nyingi, Paulo Muoka Nzili and Jane Muthoni Mara argued that it was an exceptional case in which the judge should exercise his discretion in their favour and the case was heard and won. Negotiations over compensation have now reached an agreement.
The British Government has agreed a multi-million pound compensation settlement for thousands of Kenyans tortured during the Mau Mau uprising.
The abuse took place under British colonial rule in Kenya during the 1950s. The Kenya Human Rights Commission has estimated that 90,000 people were killed or maimed and 160,000 were detained during the uprising.
Attempts by British colonial authorities to cover-up the brutal killings of 11 prisoners during the Mau Mau uprising in Kenya have been exposed in previously secret Government documents.
No-one has ever been prosecuted for the deaths even though evidence showed the detainees at Hola detention camp were clubbed to death by prison warders in March 1959 after they refused to work.
The Foreign Office files, released by the National Archives, showed British officials attempted to blame their deaths on "drinking too much water" rather than violence, and refused to identify individuals involved.
