Queen Mary, 51, in a blue skirt suit and dress hat, tiptoed up the stairs into Christiansborg Palace in Copenhagen in towering stilettos, alongside husband Frederik, who looked suave in a navy suit.

The royal couple were joined by their son, the newly appointed Crown Prince Christian, 18, as well as Frederik's mother Queen Margrethe, who officially stepped down on Sunday after a 52 year reign.

Also joining the royals at the Danish parliament was Frederik's brother Joachim, 54, who appeared at the ascension without his wife Princess Marie,  and Princess Benedikte, who is Margrethe's sister.

Joachim, who famously fell out with his mother when his children lost their Prince and Princess titles, appeared to show it was all water under the bridge as he proudly stood alongside her today. 

Once inside, the family listened to speeches from Danish politicians, including the Prime Minister, before the Danish National Girls' choir sang Hans Christian Andersen's 'Denmark, my Fatherland,' causing Mary to cry.
