The Democratic Alliance (Greek Δημοκρατική Συμμαχία) is a centrist political party that was founded by ex-New Democracy MP Dora Bakoyannis.
Bakoyannis was defeated for the leadership of the New Democracy party by Antonis Samaras. Subsequently, she refused to follow the party line and was finally expelled in May 2010 after she voted in Parliament for the European Union loan package and associated austerity measures.
She formed Democratic Alliance on November 21, 2010. The party attracted another three MPs who were ousted from New Democracy and is thus represented by four MPs in the 2012 Hellenic Parliament.
