According to the BBC World Service, a certain proportion of the funds were siphoned off to buy arms for the Tigrayan People's Liberation Front. This coalition battled at the time against Derg. The Band Aid Trust complained to the BBC Editorial Complaints Unit regarding the specific allegations in the BBC World Service documentary, and their complaint was upheld. In 2010 the BBC issued an apology to the Trust and stated there was no evidence money had been diverted, while the former British Ambassador to Ethiopia, Brian Barder, states, "the diversion of aid related only to the tiny proportion that was supplied by some NGOs to rebel-held areas."
