New government is determined to end five years of difficult economic measures

Greek left-wing leader Alexis Tsipras was sworn in on Monday as the prime minister of a new hardline, anti-bailout government determined to face down international lenders and end nearly five years of tough economic measures.

The decisive victory by Tsipras' Syriza in Sunday's snap election reignites fears of new financial troubles in the country that set off the regional crisis in 2009. It is also the first time a member of the 19-nation euro zone will be led by parties rejecting German-backed austerity.
