Greece's far-left Syriza party leader Alexis Tsipras has told Greeks the country will leave austerity behind in his victory speech. The party will have 149-151 seats in the 300-seat parliament, according to the official projection.
Alexis Tsipras has spoken to huge crowds after his Syriza party won the Greek snap election.
Tsipras said that Greece was leaving austerity behind.
It is understood the mobile number given out to the hoax caller for GCHQ director Robert Hannigan was for an unclassified phone rather than one of the secure lines used for sensitive communications.
The outgoing Prime Minister Antonis Samaras says he respects the decision of the Greek people and says that his party, New Democracy, are willing to play a role as guarantor of European stability.
Security procedures at Downing Street and GCHQ are being reviewed after two hoax calls were made to the Prime Minister and GCHQ today.
A government spokeswoman said a notice had also "gone out to all departments to be on the alert for such calls".
A hoax caller was put through to David Cameron's phone after claiming to be the director of eavesdropping agency GCHQ.
The Prime Minister ended the call when it became clear it was a hoax and no sensitive information was disclosed, Downing Street said.
Security procedures are being reviewed at both No 10 and GCHQ, where a mobile phone number for director Robert Hannigan was disclosed to the caller.
Greek Prime Minister Antonis Samaras has called Syriza leader Alexis Tsipras to congratulate him on winning the election, a Syriza spokesman has said.
Greece's far-left Syriza party will have 149-151 seats in the 300-seat parliament after winning a 36.5% share of the vote in the snap general election, according to the official projection.
The conservative New Democracy party is predicted to have come second with 27.7%.
