Melis Sekmen, a former Green Party member who recently switched to the CDU, faced intense scrutiny on the TV show 'Markus Lanz'.

Sekmen struggled to justify her party switch, citing vague concerns about integration policy and social welfare.

Host Markus Lanz challenged her consistency, pointing out that she had previously demanded a local politician resign for a similar party switch.

Labor Minister Hubertus Heil and journalist Michael Bröcker joined Lanz in questioning Sekmen's decision, emphasizing that she was elected as a Green Party candidate.

Sekmen's attempts to defend her actions were met with skepticism, leaving her visibly frustrated by the end of the show.
