On Wednesday 29 May, The King opened Stockholmia 2019 – an international stamp exhibition – at the Stockholm Waterfront Congress Centre.
The exhibition was arranged in Stockholm as an international celebration of the world's oldest stamp association, London's Royal Philatelic Society, which is celebrating its 150th anniversary this year.
The King was welcomed by manager of the Stockholmia 2019 exhibition Jonas Hällström, Director of the Waterfront Congress Centre Maria Tullberg, President of the Royal Philatelic Society Patrick Maselis and Assistant Keeper of the Royal Philatelic Collection Rod Vousden.
In his opening speech, The King said:
"Compared to Britain, Sweden does not have a strong royal tradition of collecting stamps. However, both my grandfather and my father entertained this noble hobby, and their collections are a part of my family's history."
