Prince Ernst of Hanover's oldest son Prince Ernst, who shares the same name as his father, is set to marry his fiancée Ekaterina Malysheva next year. The 33-year-old proposed to the Russian designer during a family holiday in Greece earlier this summer on the island of Spetses.
The wedding is expected to take place next summer, most likely at the Marienburg Castle in Germany. The castle is currently owned by the groom-to-be and serves as the official seat of the Royal House of Hanover.
Ernst and 30-year-old Ekaterina have been in a relationship for almost five years. They currently live in London where Ernst works in banking.

Ekaterina, who was born in Russia but grew up in Prague, moved to the UK when she was 19 to study at the London College of Fashion. She founded her clothing company EKAT in 2013.
Celebrities who have worn her striking designs include Sienna Miller, Poppy Delevingne, Rita Ora and Ella Eyre, some of whom may be invited to the wedding. Fashionistas will also be dying to know what Ekaterina wears on her big day, how many dresses she'll have, and whether she'll design them herself.

The groom's godfather King Felipe of Spain is also expected to feature on the guest list.
Princess Caroline of Monaco would not attend given that she is estranged, but not divorced, from her husband Prince Ernst. The pair married in 1999 but split ten years later.
