- It is important to raise the memory of what happened so that we never forget, he said at a press conference on Utøya.

- When we now say that we must never forget what happened, we must also live up to that promise.

He said when he was welcomed on the quay that it is a great honor to be with such a day.

- Norwegian and Swedish labor movements are so close to each other, so for me it was obvious.

The sun shines the day before the tenth anniversary.

It is almost windless and the only thing that can be heard are the small waves that hit the quay from time to time when a motorboat passes by outside the island.

Stefan Löfven was received by representatives of the Labor Party and survivors of the terrorist attack in 2011 and participated in a wreath-laying ceremony at the Lysningen memorial.

"Our most fundamental value is the equal value of all human beings," said the Prime Minister.

- We are different, thank goodness - the difference enriches us - but the value is the same and these young people stood up for it.

Always serious

Tomorrow it is ten years since right-wing extremist Anders Behring Breivik shot dead 67 people on Utøya.

The victims, who were mainly children and young people, were present at the Labor Party's youth union AUF's annual summer camp.

Anders Behring Breivik, who now goes by the name Fjotolf Hansen, was disguised as a police officer when he committed the act.

Before the massacre on the island, he had detonated a bomb in the government quarters in Oslo, in which eight people were killed.

- It is always serious when you come here, but Utøya is today a place with vitality and power.

Here, the youth have taken back Utøya with a dignity and faith in the future that inspires, said the Labor Party's party leader Jonas Gahr Støre to TT when he arrived in Utøya.

Like everyone else, he arrived on the island with the boat MS Thorbjørn, the same boat that the terrorist used to get over to Utøya during the terrorist attack.

- We must remember the worst attack on Norway since the Second World War, we must have that with us.

There are many who experience loss and grief, especially on a day like this, said Jonas Gahr Støre.
