At the end of World War II, neither the British nor Norwegian Governments made any public acknowledgement of the close cooperation between SIS and SOE, and the Norwegian Resistance groups, the Linge Company and Milorg. This was unfortunate given the significant contribution of their work to the Allied War effort but was due to the secrecy surrounding British intelligence operations. The situation has now changed, and it has become possible to acknowledge the extent of the remarkable achievements on which Britain and Norway cooperated. The Anglo-Norwegian Commemoration Project, of which Her Royal Highness The Princess Royal became Patron in 2023, has the aim of increasing public recognition of this important chapter in the history of Norway and the United Kingdom.

Her Royal Highness has met many of the key figures of the Norwegian Resistance such as Joachim Rønneberg, and has heard a number of speeches highlighting Operation GUNNERSIDE, the SOE Operation to disrupt the supply of Heavy Water to Germany. She has also previously met numerous members of the Norwegian Special Forces.
