Kildare-born Ned Guinness, also known as Lord Iveagh, has seen the family stake in drinks giant Diageo increase in value by about €40m in the past year. He's one of Britain's biggest private landowners, as his vast Elveden estate in Suffolk covers 22,500 acres and grows potatoes and 10pc of all the onions consumed in the UK. Customers include McDonald's, Sainsburys and Walkers Crisps. The estate's Elveden Hall has starred in various movies.
There is also a farm in Co Meath, run by his brother, while he was also interested in buying nearby €60m Carton House. In Dublin, Iveagh Trust has also set a target to build 2,020 affordable homes by 2020, and is working with developers including Gerry Gannon, Michael Cotter and Cairn Homes to achieve that.
In recent years, Guinness emerged as a significant backer of Irish firm Blueface, which provides internet-based phone services to businesses and expanded into the US, Spain, Germany and France in 2016.
There is also property in Britain, including BGL Golf, which owns 22 golf courses, making it one of the country's largest operators. In Canada, meanwhile, its British Pacific Properties owns over 4,000 acres and specialises in high-end housing in and around west Vancouver. Its assets are likely to have increased in value, as will have any other family wealth. There are parks and a shopping centre as well. He owns some eclectic cars: an old Nissan Micra, a newer 4x4 and a green 1928 vintage Rolls-Royce.
