Jakob Augstein and Nikolaus Blome joked the UK had “shot themselves in both feet” and would need to be “damaged” by the EU for leaving the bloc to prevent other members states taking the same path.
In a programme called ‘Make Britain Small Again’, Augstein attempted to sing the chorus of ‘Rule, Britannia!’ before taking a swipe at the UK’s move for independence.
Augstein asked whether Blome was inspired by the English because they were “courageously” headed “towards their own doom”.
While blowing up a make-shift crown, Blome replied: "Well it takes a lot of courage to assemble behind a Queen who is silent and to close the bridge to Europe.

“To swim towards the Atlantic in the fog and not to arrive in Newfoundland because nobody there is waiting for the English.”
Augstein, a journalist and publisher, said the Queen had “failed” the country for not standing up against Brexit.
He said: “I think it’s interesting that you started with the Queen because, you’re right, she completely and utterly failed.

“But now it is really about limiting the damage because there will be damage to both sides.”
Augstein then cut back by saying a “little bit of damage” was necessary to put other European Union member states off exiting the union.
He said: “Careful! A little bit of damage, I'm sorry even if this sounds a little bit strange. But there should be a little bit of damage because otherwise the Hungarian or the French or even the Italians could start thinking ‘hey, that's great, the British got a fantastic deal.”
He added if the bloc relieved Britain of its debts and offered it a trade perk then it could incentivise other countries to leave the bloc.
