Greek election: The financial fallout of Syriza's win
The far-left Syriza party, which won Greece's general election on Sunday, has formed an anti-austerity governing coalition with the right-wing party Greek Independents.
Syriza leader Alexis Tsipras has vowed to renegotiate Greece's bailout, worth €240bn (£179bn; $268bn), to end Greece's "humiliation and pain".
The new government in Greece is now the first in the EU to reject its bailout deal while other weak economies like Spain and Italy are still tied into large debt repayments.
