The 23-year-old, who had finished ninth in the previous day’s individual event won by her elder sister Hanna, the 2018 Olympic individual champion, produced a typically powerful skiing display to bring her team home.

Using six spare rounds, the quartet of the two Öbergs, Linn Persson and Anna Magnusson finished in 1 hour 14min 59.8sec.

It was the third Swedish win from the four competitions that have so far been contested in Kontiolahti.

Regarding her ninth place, Öberg - who won two individual silver medals at the Beijing 2022 Winter Olympics as well as partnering her elder sister in the title-winning 4x6km relay team, told the IBU: "Yesterday was not a catastrophe.

"It was a decent race but I want to do more than ninth place.

"What I did today is more like what I want to do."

Germany, with a fast final loop by Denise Herrmann-Wick, finished second, 28.1sec back.

Norway, with three spares, finished third, 31.5 off the leaders.

There was no Swedish victory in the men's race as Norway powered to victory.

Vetle Sjåstad Christiansen, Sturla Holm Lægreid, Johannes Thingnes Bø and Tarjei Bø completed the course 43.9 ahead of their closest challengers.

Germany were once again second and France third.

These were the first relays of the IBU World Cup season.

Tomorrow is a rest day.
