Alexis Tsipras was on Monday sworn in for the second time as the prime minister of Greece, after winning a snap election.
He said he planned to form a government with former junior coalition partner, the Independent Greeks.
A breakaway anti-austerity faction of SYRIZA that formed its own party failed to secure any seat in Parliament in Sunday’s elections.
Tsipras warned that there would be no “magic solution” that would allow Greece to emerge from its economic crisis quickly.
He promised, in his victory speech, that he would overturn entrenched politics and support long-struggling Greeks.
The polling, in which SYRIZA garnered 35.5 per cent of the votes compared with the conservative New Democracy’s 28, had the lowest turnout in Modern Greek history with less than 57 per cent of the electorate casting a ballot.
