Arthur Kemp is a British writer and the owner of Ostara Publications who was from 2009 to 2011 the foreign affairs spokesperson for the British National Party before resigning from that party. He was born in Southern Rhodesia (Zimbabwe) and worked as a journalist in South Africa before moving to the United Kingdom.
Kemp was born in Southern Rhodesia, spending his formative early political years in South Africa. Kemp worked as a journalist for the South African Conservative Party, which opposed South Africa's transition to universal suffrage. Kemp also wrote for The Citizen newspaper.
Kemp was conscripted and served as a sergeant in the South African Police in Johannesburg from 1987 to 1988.
In 1993, Kemp was a prosecution witness in the trial relating to the murder of the South African Communist Party leader Chris Hani. Kemp gave evidence against Clive Derby-Lewis and his wife saying they admitted their involvement during a lunch the three had together two days after Hani's death. Clive Derby-Lewis and the actual assassin, Janusz Walus, were found guilty and sentenced to death (both death sentences were later commuted to life), while Gaye Derby-Lewis was acquitted.
