COPENHAGEN (Reuters) — Helle Thorning-Schmidt said on Sunday that she had agreed with political allies to form a three-party center-left coalition government, after a decade of center-right rule in Denmark.

Ms. Thorning-Schmidt, the leader of the Social Democratic Party, will be the first woman to serve as Denmark’s prime minister. She said on Danish television that she had completed a policy program “that will bring Denmark out on the other side” of its economic crisis. “With this program, we can modernize Denmark,” she said before paying a brief visit to Queen Margrethe, who gave her formal approval.

The coalition includes the Social Democrats, Socialist People’s Party and Social Liberals.
