Robert Habeck, Federal Minister for Economic Affairs and Energy, says Patrick Graichen has made himself too vulnerable to be able to exercise his office effectively. "It's one mistake too many.

That's why I made this decision today. It's a far-reaching, difficult decision – far- reaching for my house, hard for me and very hard for Patrick. Graichen," he says. "This is not how political debates can and must not get out of hand. I will now appoint a successor quickly"
