An MP from one of Germany’s governing parties has left his longtime partner and three children for a porn star.

Hagen Reinhold, 44, of the centrist Free Democratic Party – part of Germany’s governing coalition – recently left his partner of 16 years and three children for adult actress Annina Ucatis, 43.

Jilted Karoline Preisler, 51 – a lawyer and fellow FDP politician – took to social media to announce her separation from Reinhold, confessing: “The past few months have been a bitter time for me.”

Weeks ago, double-G-cup Ucatis had raised eyebrows by announcing that she would run for the FDP in local elections in Elmshorn, Schleswig-Holstein, next year, having joined the party in 2021.

Reinhold – a member of the Bundestag since 2017 – told local media: “We got to know and love each other in the FDP.”

Ucatis – an economics graduate – has starred in several pornographic films and was once a contestant on Promi Big Brother, Germany’s answer to Celebrity Big Brother.

She also runs her own real estate agency called Holsteiner Grund & Boden.

Ucatis had married real estate billionaire Theodor Semmelhaack, 65, in 2013, but the couple recently separated.

Of her new romance, she told local media: “It’s a great love and we’re going into a happy future together.”
