Queen Mary of Denmark beams in cool green as she attends the opening of Parliament with King Frederik

Queen Mary looked elegant in a mint green ensemble as she attended the state opening of parliament with her husband King Frederik and his aunt Princess Benedkeek.

The Danish queen, who shares four children with King Frederik, looked typically stylish in a coat dress and matching hat with brooch.

Mary, 52, and Frederik, 56, sat separately, according to royal protocol, after greeting Benedkeek, 80, outside the seat of the Danish parliament, Christiansborg in Copenhagen

Queen Mary’s coat dress had a belt at the waist and fell just below the knee.

The Australian-born royal wore her long brown hair in a dry bow under her hat and carried a bouquet of pink flowers.

The three Danish monarchs sat separately in the upper gallery, although Mary and Frederik were seen leaning over the empty chair between them to talk.

Queen Mary chose a knee-length, mint green coat dress for the formal occasion, while Princess Benedkeek looked equally elegant in a cream tweed suit. King Frederik, meanwhile, opted for a three-piece navy suit

King Frederik wore a three-piece navy blue suit, complete with a light blue shirt and a bronze tie.

His aunt, Princess Benedkeek, looked equally chic in a cream tweed skirt suit, which she teamed with a sky blue hat and matching scarf.

She wore a pair of diamond earrings and a quilted Chanel handbag.

Margarethe, 84, a distant cousin of the late Queen Elizabeth II, announced her abdication on New Year’s Eve after ruling for 52 years. This made her the second longest-reigning Danish monarch.

She was recently hospitalized after a fall and is doing ‘very well’, although she was not present today.

Gathering for the opening of the Danish parliament, which takes place on the first Tuesday in October, the royals were joined by Prime Minister Mette Frederiksen, who arrived with her husband Bo Tengberg, 59.

Mette Frederiksen, the youngest prime minister in Danish history, was dressed in a dark pink trouser suit, while her husband looked dapper in a dark suit and tie.

With her combed back hair, natural make-up and a broad smile, Prime Minister Frederiksen cut a stylish but accessible figure.

Last week, Mary provided an informal update on her mother-in-law’s health.

The 56-year-old king acceded to the throne on January 14 after his mother, the second-longest-reigning Danish monarch, abdicated.

He appeared cheerful and smiling as he made his way to the seat of the Danish parliament, Christiansborg in Copenhagen

Speaking before the National Conference for Health Visitors in Copenhagen on Monday 23 September, Queen Mary said: ‘Considering the circumstances, she is doing very well.

“I’ve been able to visit her a few times since she came home. She is super cool and keeps her spirit high. Thanks for the question.’

On September 23, Queen Mary attended the National Health Visitors Conference with The Mary Foundation, which was likely her first appearance since Queen Margrethe was discharged from hospital.

It was believed that all of Queen Margarethe’s public appearances had been canceled to give her time to recover.

Frederick said he had spoken to his mother and believed she was “in good hands.”

He added: “We are taking it day by day. It is the doctors who decide.’

The king spoke as he arrived at the Danish capital’s City Hall to attend celebrations marking the 100th anniversary of the Copenhagen Royal Chapel Choir.

Queen Margrethe, a third cousin of the late Queen Elizabeth, is known for her chain smoking and love of dachshunds.

Despite renouncing her New Year’s Eve speech late last year, the former monarch continues to carry out royal duties alongside her son and Queen Mary.
