French President-elect Francois Hollande is to start work on forming a new government, after telling supporters his victory gave hope of an end to austerity.
Hollande has vowed to rework a deal on government debt in eurozone member-countries to focus on promoting growth.
The Socialist leader won just under 52 percent of votes in Sunday’s run-off election.
Center-right incumbent Nicolas Sarkozy is the first French president since 1981 not to win a second term.
He will hand power to Hollande on May 15, following talks between the two camps, the presidency has said.
