Oliver Welke of the Heute Show said only the Nazi leader had made more mistakes during his reign than Mrs Merkel. The popular evening talk show host lambasted Mrs Merkel, who is plummeting in opinion polls due to her open-door migrant policy. He said she had “ruined everything that is near and dear to us”, a damning criticism by one of the country’s most popular television figures.

Mr Welke said on Friday: “Let me tell you this: since Hitler, no other person has been as much at fault for anything like this. Yes, it’s true!”

He blasted Mrs Merkel for failing to acknowledge she had made an error in opening Germany’s borders last year, resulting in more than one million migrants arriving in the country in the months since. He said: “Merkel stubbornly sticks to her policies. Why? Why is this woman, despite the catastrophe, not able to bite the bullet and say ‘Yes we made a mistake. We shouldn't have opened the borders’.

“It’s not going to hurt her. It’s possible to correct oneself, isn’t it? “You can't integrate everyone. One year of 'We can do this' - with only three words and five selfies, this woman has ruined everything that is near and dear to us.” He also accused Peter Altmaier of having “some very disturbing arguments”, before playing a clip showing the Chancellery Chief defending Mrs Merkel.

In the club, Mr Altmaier said: “Look, Germany is such a great country. Because in Germany we don't just have one Angela Merkel but ten of thousands, hundred of thousands of Angela Merkels. “In every town, in every city. The Mr District Administrator has one at home, Mr Mayor has one at home.” To applause and laughter from the crowd, Mr Welke joked: “Holy s**t! Do I have one at home as well?”
