A collection of luxury cars seized from Equatorial Guinea's vice president Teodorin Obiang Nguema will be auctioned off in Switzerland on Sunday and are estimated to bring in £15.2 million.

"This is an exceptional sale," said Philip Kantor of British auctioneers Bonhams. "It's a private collection of supercars, with very low mileage."

Among the cars to go under the hammer at a Geneva golf club include seven Ferraris, three Lamborghinis, five Bentleys, a Maserati and a McLaren.

The most expensive lots are a Lamborghini Veneno Roadster, valued at between 4.8 and 5.7 million euros and yellow Ferrari hybrid at 2.4 and 2.6 million euros.

The cars were all confiscated by Swiss justice after the opening in 2016 of a financial wrongdoing case against Obiang, son and likely heir of Equatorial Guinea's authoritarian President Teodoro Obiang Nguema who has ruled for 40 years.
