How did Alexis Tsipras survive the January 2019 vote of confidence?

Alexis Tsipras survived the January 2019 vote of confidence by securing a narrow 151–148 victory in the Greek parliament.1

This political crisis was triggered when the Prespa Agreement—a deal to resolve the long-standing dispute over the name of North Macedonia—faced imminent parliamentary approval. In protest of the agreement, Defense Minister Panos Kammenos resigned, and his party, the Independent Greeks, withdrew from the ruling coalition. This departure eliminated Tsipras's already slim majority and left his government facing potential collapse.1

To maintain control and ensure the agreement could proceed, Tsipras called for the confidence vote. He successfully remained in power by retaining the support of independent members of parliament and rebellious members of the Independent Greeks.1
