Prince Oscar of Sweden proved himself to be the cutest Christmas elf as he helped his big sister and mum choose a Christmas tree on Thursday.

The one-year-old prince joined his sister Princess Estelle, five, and mother Crown Princess Victoria, 40, for the annual Christmas choosing tradition for the first time last week.

The trio put on a festive display with Victoria, who is first in line to the throne, dressed in a full red skirt and black fur jacket for the annual family tradition.

On Thursday Crown Princess Victoria was joined by her children Prince Oscar and Princess Estelle to select Christmas trees for the royal palace in Stockholm

Estelle, who has been attending the tradition since age one in 2013, looked adorable in a matching red dress paired with white tights and a navy wool coat to keep out the chill.

For his debut at the ceremony Prince Oscar was adorable in a grey cardigan, blue shirt and thick navy duffle coat.

The tradition sees the Swedish royal family welcome students from the master's program at the Swedish University of Agricultural Sciences (SLU).

The students present the royals with a selection of Christmas trees which they will then choose from to have displayed in the royal palace in Stockholm.

The children appeared delighted to meet the students who were dressed like Christmas elves for their visit to the palace.

Even at the young age of one it seems that Oscar has already inherited his mum's impeccable manners seen shaking hands with one of the students while choosing from the trees.

Since the late 1960s, SLU has presented Christmas trees to the Royal Palace. The King's Cave has got its current name according to this tradition, it was originally called Nordmann's branch.

Much like the Queen's Christmas Day speech, the Swedish royal family release a Christmas message a few days ahead of the big day where they reflect on the year that's gone and the one ahead.

On 23rd the family celebrate the birthday of Queen Silvia, who will turn 74 on Saturday, with a German fruit cake served in a nod towards her heritage.
