Greece's Interior Minister Nikos Voutsis said on Saturday that Athens will reach a new debt deal with its creditors this week.

"We believe that we can and we must have a solution and a deal within the week," Voutsis noted.

The Greek interior minister is not involved in talks.

"Some parts of our program could be pushed back by six months or maybe by a year, so that there is some balance," he added.

Voutsis did not point out what parts of the anti-austerity program could be pushed back.
