The deal with Jersey, a self-governing island in the English Channel, has been hailed as "a victory for the people of Kenya" by its High Commissioner in the UK, Manoah Esipisu.

He signed the deal in London with Jersey’s Attorney General Mark Temple.

The agreement has international treaty status, and also involves the governments of the UK and Switzerland.

The deal covers more than $4.9m (£3.6m) seized from a bank account belonging to Samuel Gichuru, the wealthy boss of Kenya's power company.

He and former Finance Minister Chris Okemo were accused of taking kickbacks from multinationals which were sent to a Jersey-registered company.

Despite repeated attempts to contact them by the BBC, both men and their lawyers would not comment on the allegations levelled against them.
