It comes after Princess Marie broke her silence on reports that she and her husband were planning to relocate to the US later this year.
The rumours surfaced at the start of the year – shortly after Joachim's four children all lost their HRH titles at the behest of the queen.
The decision, when it was announced, caused great controversy amongst the royal family, with Joachim, Marie, and his ex-wife Alexandra, Countess of Frederiksborg, all speaking publicly of their upset.

Joachim and Marie stepped back as full-time working royals in 2019 to move to the French capital.
Prior to that, he completed military training before taking up the job at the Danish Embassy in Paris as defence attaché. His position is set to come to an end this summer.
