Austria's first three-party government since the aftermath of World War Two took office on Monday, ending the country's longest-ever wait for a ruling coalition and keeping the Russia-friendly, far-right Freedom Party (FPO) out of power.

Austria's new three-party coalition government comprising the conservative Austrian People's Party (ÖVP), the Social Democratic Party (SPÖ) and the liberal NEOS was sworn in on Monday, ending months of political deadlock in the Alpine nation.

Three parties say they have reached a deal to form a new centrist Austrian government, five months after an election was won by a far-right party that later failed in an attempt to form an administration.
