Serbia's president has formally nominated the highly conservative country's first openly gay prime minister.
Vucic calls it "a difficult decision reached in the interest of Serbia and its citizens." Brnabic is currently government minister of public administration and local government.
Brnabic's appointment for the government last year was hailed by rights groups as historic for the Balkan country whose gay community often faces discrimination, harassment and violence.
Vucic, a former extremist-turned-reformist, has promised to boost gay rights as part of efforts to move closer to European Union membership.
