Athens also confirmed it expects to report a budget surplus excluding interest payments of 2.9 percent of GDP next year, just shy of the 3 percent target set under the country's 240-billion-euro EU/IMF bailout.

Unemployment is expected to fall to 22.5 percent in 2015 from 24.5 percent this year, while debt is expected to fall to 168 percent of GDP from 175 percent this year, the draft budget said.
