ATHENS (AP) ― Greek Prime Minister George Papandreou has called an emergency cabinet meeting for Thursday as his governing Socialist lawmakers revolt against a referendum plan.

A statement from Papandreou’s office says the meeting will be held at noon and comes after Finance Minister Evangelos Venizelos broke ranks with the prime minister on the referendum proposal.

Earlier Thursday, Socialist lawmaker Eva Kaili also said she would not support the government in Friday’s confidence vote.

Kaili urged Papandreou to reverse his decision to call a referendum on Greece’s hard-won international bailout package.

Without Kaili’s support, the governing Socialists hold a one-seat majority in the 300-member parliament.
