When his father was Vice President, Hunter Biden was doing business in a fourth cash-soaked but highly corrupt country Kazakhstan.

Between 2012 and 2014, Hunter worked as a sort of go-between for Kenes Rakishev, a self-styled 'international businessman, investor and entrepreneur' with close family connections to the kleptocratic regime of his homeland's despotic former president Nursultan Nazarbayev.

Emails passed to this newspaper via anti-corruption campaigners from the Central Asian country reveal that Biden Jr held extensive meetings with Rakishev, who was looking to invest a portion of his personal fortune in New York and Washington DC. He also travelled to the Kazakh capital of Astana to hold business discussions.

Hunter Biden then attempted to persuade Rakishev to buy into a Nevadan mining company, brokering a series of meetings with the firm, before convincing him to invest a cool million dollars with Alexandra Forbes Kerry, the film-maker daughter of Democrat Senator and former Presidential candidate John Kerry.
