Tanzania’s High Commissioner to Cuba, Humphrey Polepole, has resigned from his diplomatic post, expressing deep concern over the country’s current leadership.

He expressed concern over Tanzania’s political trajectory under the ruling Chama Cha Mapinduzi (CCM) party.

In a resignation letter dated July 13, 2025, Amb. Polepole cites increasing human rights abuses, erosion of accountability, and a lack of respect for human dignity as key reasons behind his decision.

"With respect and humility, I wish to inform you that I have reached the decision to resign from my role in public leadership as Ambassador and Head of the Diplomatic Mission of the United Republic of Tanzania in Havana, Cuba. This includes my representation in the Caribbean, Central America, and the friendly countries of Colombia, Venezuela, and Guyana," reads the statement written in Swahili.

The envoy stated the decision follows deep reflection on the current trajectory of leadership in the country, as well as his personal experiences, as a Member of Parliament in the Parliament and subsequently as Ambassador in missions in Lilongwe, Malawi and in Havana, Cuba.

He highlighted the "immeasurable honor" of being entrusted with the responsibility of serving in such a high office.

However, he added that throughout his time serving both at home and abroad, he has closely observed and with deep regret, witnessed a concerning trend in leadership—one that lacks proper commitment to defending people’s rights, peace, and human dignity.

"There has been a noticeable erosion of genuine resolve and accountability in addressing the public’s concerns and challenges, alongside a decline in ethical leadership across various levels. The weakening of the government’s core responsibilities in safeguarding citizens' welfare threatens the broad interests of the United Republic of Tanzania," continues the statement.

"All of this has increasingly robbed me of peace of mind and confidence in the leadership I am currently part of."

The Ambassador also expressed concern over how the ruling party, CCM, conducted its nominations, ahead of elections in October this year.

"Recent events have clearly violated the principles, culture, and traditions of Chama Cha Mapinduzi (CCM)—particularly in the nomination process of candidates within the Party," he said.

In his letter, Polepole also roundly criticized the Tanzanian government for not upholding principles of the national and party constitutions.

"Since I can no longer be part of a leadership that does not uphold the principles of the national and party constitutions, justice, ethics, human dignity, and accountability to the people, I have voluntarily decided to resign from my leadership and executive role in government," he remarked.

The envoy says he'll continue being an ordinary CCM Party member, despite the decision.

"I will continue to be an ordinary CCM member, a patriot, and a loyal citizen of our nation," said Polepole.
