She has previously been criticized for attending too many music festivals & spending too much on partying instead of ruling.

Commenting on the video, 36-year-old Ms Marin who was once dubbed “the coolest prime minister in the world” by Bild, said she did not do anything wrong.
"I danced, sang, and partied - perfectly legal things. And I’ve never been in a situation where I’ve seen or known of others using drugs," Ms Marin said.
“I have a family life, I have a work life and I have free time to spend with my friends. Pretty much the same as many people my age."
Ms Marin also hit out at whoever published the video as it had been taken at a private event.
Although she did not break any rules at the time, she later apologised.
