Ned Guinness (47), the Earl of Iveagh, is the heir to the Guinness brewing fortune. The family is said to hold a near €300m stake in global drinks group Diageo, which now brews Guinness.
Guinness owns the hugely valuable Elveden Estate in Suffolk, making him one of the biggest private land-owners in the UK. Elveden is a massive 22,500 acre agri-business enterprise growing 10pc of all the onions consumed in Britain.
Guinness also chairs the €300m Iveagh asset management group. He is also an investor in Alan Foy’s telecoms group Blueface, based in Dublin’s docklands. The Earl ran the 2008 Dublin marathon dressed as a colourful Toucan – an emblem of Guinness stout.
