In a statement after the meeting, Venizelos stressed the need for Greece to take to the fullest advantage the "window of opportunity" opened up by the eurozone summit decisions.
He also said that the opposition parties must be fully informed so that "this historic, nationwide effort" for the country's exit from the crisis may be built.
"We are at a very delicate phase, given that the conjuncture is very difficult not only for Greece but also for other countries of the eurozone," Venizelos pointed out.
"We have taken a breath," Karatzaferis said in turn, stressing that the outcome of the effort depends on everyone, both "the government that must show seriousness and strength", and "the opposition, whose contribution is necessary".
On LAOS' stance, Karatzaferis noted that it criticises when necessary, and lends support when it believes this will be to the country's benefit.
