A senior official of Greece's ruling Syriza party attacked the latest proposals from international lenders as "blackmail" on Thursday, highlighting the deep divisions between Athens and its creditors as wrangling continued over a bailout deal. "The lenders' demand to bring annihilating measures back to the table shows that the blackmail against Greece is reaching a climax," Nikos Filis, the ruling Syriza party's parliamentary spokesman told Mega TV.
