Despite Greek political leaders finally agreeing on austerity measures to secure a second bailout, eurozone finance ministers meeting in Brussels are wavering on whether to green light the loans.

Final word still needs to be given by European finance ministers, who are meeting in Brussels. Greek Finance Minister Evangelos Venizelos, arriving for the meeting, said Greece "now needed the political endorsement of the eurogroup for the final step."
