It will be King Philippe’s first visit to the Democratic Republic Congo since ascending to the throne in 2013.

The trip - postponed by the pandemic - has been hailed by the presidency as an opportunity for reconciliation.

Two years ago the king wrote to President Tshisekedi, expressing his deepest regret for "the wounds of the past".

Belgian Prime Minister Alexander De Croo, who is also part of the delegation, has called it a historic moment and an opportunity to forge closer ties.

The king is also due to discuss the question of returning artworks looted during the colonial era.

That past remains painful.

Millions of Congolese suffered acts of cruelty, particularly during the reign of King Leopold II, who owned the Congo Free State as his personal property.
