In an exclusive interview, the heir of Theo Albrecht, who founded the discount supermarket chain Aldi, discusses the family feud being waged with his sister-in-law Babette and how he is protecting the €50-billion business from the family. This is a first. Theo Albrecht Jr., co-owner of Aldi Nord and one Germany’s richest people, has never given an interview before. The family is normally intensely private. But at the moment, it is in the midst of a bitter feud, and, for the first time, he has gone public to make his position clear.
