Delia Smith and Michael Wynn Jones will no longer be majority shareholders in Norwich City after Mark Attanasio's increased stake was approved.
The Milwaukee Brewers owner joined the Canaries board last September when the American bought 15.9% of the club.
His Norfolk FB Holdings group have now acquired an additional 195,012 shares for about £6m, bringing him level with the 40% of Smith and her husband.
The deal was ratified at a meeting of shareholders at Carrow Road on Monday.
Smith, her husband Wynn Jones and Attanasio were not present at the meeting at which which votes were cast on five resolutions, with others already having done so by proxy.
