The 53 special phones are to be supplied by Amjad Ali, a Bristol-born owner of Gold and Co. based in Dubai.
Ali, who told The Independent that his firm was “fulfilling an order from the Nigerian government for 53 gold-plated iPhones, added, “We will engrave them with the coat of arms, a shield and two horses. “
However, he neither disclosed when he received the order for the item nor the Federal Government agency or ministry that contracted him.
Gold and Co supplies royal families, governments, and minted customers across Russia, China and the Middle East with special phones.
