Swiss food giant Nestle on Monday dismissed Laurent Freixe as chief executive with immediate effect over an “undisclosed romantic relationship with a direct subordinate”.

The multinational behind Nespresso coffee capsules and KitKat chocolate bars said Freixe’s dismissal followed an investigation.

In a swift move, Nespresso CEO Philipp Navratil was appointed to take over by his fellow board members.

“The departure of Laurent Freixe follows an investigation into an undisclosed romantic relationship with a direct subordinate which breached Nestle’s code of business conduct,” a statement said.

The board said it had ordered an investigation overseen by chairman Paul Bulcke and lead independent director Pablo Isla, with the support of outside counsel.
