The leadership crisis resurfaced in mid-2021, when pro-Auyk Tabe AGovC announced an alliance with the Indigenous People of Biafra (IPOB), a Biafran independence movement. Sako denounced the alliance on grounds of the importance of goodwill from Nigeria, and argued that AGovC had put the hundreds of thousands of Anglophone refugees in Nigeria at danger. The AGovC fired back, stating that "those who liberated Rwanda came from refugee camps in Uganda" and that "Nigeria has shown itself not to be our friend". IPOB also dencounced Sako's claim to the Ambazonian presidency, declaring him one of many "traitors and selfish fellows".
