Compared to the outgoing cabinet, there are seven new faces.Among the new arrivals are Labour Minister Hanne Bjurstroem, who had headed up Norway's climate negotiations, and Defence Minister Grete Faremo, a veteran Labour Party member.
The Labour Party, which was the big winner in the September 14 election, will head up 12 ministries including three of the most important.
In addition to Stoltenberg keeping the post of prime minister, the Labour Party retains the foreign ministry, held onto by Jonas Gahr Stoere, and the finance ministry, which is being taken over by another veteran party member, Sigbjoern Johnsen.
The Socialist Left Party lost one ministry and now controls four, the same number held by the Centre Party, which hangs onto the petroleum and energy ministry, a key post in Norway which is one of the world's biggest exporters of oil and gas. Several ministers will also swap portfolios, including the heads of the Socialist Left and Centre parties, Kristin Halvorsen and Liv Signe Navarsete. The former will change from finance to education minister while the latter will go from transport and communications to regional affairs minister.
In the general election, the left-wing coalition won a narrow majority of 86 out of 169 seats, after a campaign during which it vowed to defend jobs and strengthen the welfare state.
