In the court yard, the king holds the so-called Court yard speech (Swedish Borggårdstalet, which crown prince Gustaf Adolf recites outside the castle to those, who do not get room at the court yard), where the king puts forth his opinion about the Swedish armed defence propagating that it should be strong, contrary to the official policy of Swedish prime minister Karl Staaff and his government of disarmament.
