"It must be strenuous to come to a new country and take on her
position," the queen told reporters at Fredensborg Palace north of
Copenhagen on the launch of a new royal biography.
"She's doing a great job, I'm a proud mother-in-law," said Margrethe,
who ascended to the Danish throne in 1972.
If Mary Donaldson, who worked as a real estate agent in Sydney before
meeting Fredrik at the 2000 Olympic games, does find her new role
difficult, the queen said she could expect it to get easier as the
years go by."
"My job has become easier as I gained more experience but it will never
become a routine for me," said the queen, who turns 65 later this
month.
Earlier this month, Frederik's younger brother Prince Joachim
officially divorced his Hong Kong-born wife Alexandra, but the Danish
royal family remains popular with a large majority of Danes.
