Top psychiatrist and best-selling author Hans-Joachim Maaz says Angela Merkel’s refusal to reverse her “completely irrational” policy on accepting migrants is evidence that the German Chancellor is undergoing a “mental breakdown”.

Maaz, who was noted for his work studying the psychological impact of government repression on the population of the former East Germany, toldHuffington Post Germany that Merkel’s “emotional” decision to open the country’s borders to a flood of refugees was an expression of her own rampant narcissism.

According to Maaz, Merkel being dubbed the “most powerful woman in the world” has left her incapable of handling criticism and prone to hubris, with the psychiatrist adding that the German leader has, “lost touch with reality.”

Facing intense criticism from the German population and from within her own party, Merkel is at risk of an “imminent” mental breakdown and now represents a “danger” to Germany, according to Maaz.

“A psychological or psychosomatic collapse is imminent,” warns Maaz, adding that Merkel’s own nervous body language in which she clutches her jewelry is also a sign of “insecurity”.

Despite Merkel’s open border policy culminating in the mass molestation of women by migrants in the city of Cologne on New Year’s Eve, the Chancellor has refused to listen to critics who have demanded she significantly scale back Germany’s acceptance of “refugees” from the Middle East and North Africa.

In the aftermath of the Paris massacre, Merkel doubled down on her policy, insisting that Germans must show “tolerance” towards migrants.

In October, top security experts warned Merkel that the middle class in Germany is becoming “radicalized” in response to the migrant influx and that domestic unrest may occur as a result.

The warning was “circulated among high-ranking security officials in the federal government,” according to the report.
