"Your message is clear." said the Crown Princess, when revealing Gardell's name. "Straighten your back. Stretch out your hand. We will wipe each other's tears". His book is called "torka aldrig tårar utan handskar" - never wipe tears without gloves - a quote based on advice to medical staff during the early AIDS crisis.
Accepting the award, to a standing ovation, Jonas Gardell said "you are our crown princess - but "but".
Victoria is the first Swedish royal to take part in one of the country's major LGBT events. Two years ago Prime Minister Reinfeldt attended to award the main prize at the event organised by magazine QX.
The Princess' appearance was welcomed by the editor of the Social Democratic tabloid Aftonbladet. Lena Melin writes that it is important to see Victoria taking a stand "all honour to Victoria". The paper's court expert, Roger Lundgren, says that this move by the Swedish royal has never happened before anywhere in the world.
Jonas Gardell's series, 'Torka aldrig tårar utan handskar' won in five categories. Comedian Soran Ismail won "Hetero of the year", after a year when he was in the news for a videoed incident, where he confronted three Sweden Democrat politicians over their racist statements.
The QX magazine's Honourary Prize went to HBTQ rights campaigners in Uganda, it was collected by Jimmy Sserwadda and Lawrence Kaala.
