Arnold made the assertion in a Facebook post titled “Britain’s Bill Is Due,” where he argued that an independent Biafra could demand what he described as the largest reparations payout in history—an amount he said is roughly double the annual GDP of the United Kingdom.
Known for his support of the Biafran movement, Arnold described Britain’s historical role in Nigeria, particularly in the South-East, as deeply unjust. He traced the roots of the issue to the 1914 amalgamation of the Northern and Southern protectorates under British colonial rule, which he claimed forced together incompatible regions for economic and political control.
He further alleged that during the Nigerian Civil War, Britain backed the federal government to protect its economic interests, especially oil. According to him, British-linked oil giant Shell-BP controlled a significant portion of oil production at the time, much of it located in Biafran territory.
Arnold accused the British government of secretly supplying arms to Nigeria during the war while publicly denying involvement, and claimed that the blockade imposed on Biafra led to widespread famine and millions of deaths, many of them children.
He also criticised Britain for allegedly failing to acknowledge or apologise for its role in the conflict, stating that the events have not been properly addressed in official records or education.
In his post, Arnold outlined how he arrived at the $6 trillion figure, describing it as a cumulative estimate based on several factors, including oil revenues from Biafran territories, compensation for lives lost during the war, long-term structural and political impacts of colonial decisions, and additional damages such as obstruction of humanitarian aid and military support to Nigeria.
He argued that when adjusted for inflation and combined with global precedents for reparations, the total could amount to one of the largest financial claims ever made, should Biafra eventually gain independence and pursue such demands.
