Greece’s government narrowly escaped an opposition vote of confidence on Friday over a wiretapping scandal that saw top officials targeted by state intelligence for months.

The motion of censure was rejected by 156 votes to 143, said the deputy speaker of the Parliament, Harlempos Athanasiou, after the official count of the votes in the Assembly.

Former leftist prime minister Alexis Tsipras released a memo on Wednesday accusing Prime Minister Kyriakos Mitsotakis of being the “computer and leader of this criminal network” that tapped authorities’ phone calls.

Mitsotakis confirmed that the wiretapping Tsipras referred to was authorized by a state intelligence agency prosecutor and therefore legal, without elaborating.

“(Surveillance) was cool. We need to clarify this issue,” said the prime minister. The events take place at a time when left and right parties have already started their pre-election campaign, although the election date has not yet been set.
