The Labour Party (Ap) has the biggest drop in the latest poll, down 4,3 percentage points. The Liberal Left (Venstre), on the other hand, has its best result since November, at 6 percent.
Although the support for the Labour Party drops by four percentage points in the poll conducted on behalf of the newspapers Klassekampen and Nationen, it remains the largest party at 37,3 percent.
Prime Minister Erna Solberg's Conservative Party (Høyre) experiences the largest increase, up 1,3 percentage points to a total of 24,7 percent.
The Liberal Left arranged its national assembly this weekend, and could celebrate 6 percent support, the party's highest result since November, and much higher than during the government election in 2013. The party moves up 0,8 percentage points from March.
"This may be a result of us standing our grounds in the issue of the asylum children," says deputy party leader of the Liberal Left Party, Terje Brevik.
