Greece's new prime minister has been sworn in after forming a surprise anti-bailout alliance with a small right-wing nationalist party.

His Syriza party gained the key backing of Independent Greeks after Sunday's elections, paving the way for a coalition government.
Tsipras won the vote but fell short of the majority needed to govern alone.
