ATHENS (Reuters) - Greek Prime Minister Alexis Tsipras urged his Syriza party lawmakers on Friday to approve a bill on pension reforms in a parliamentary vote on Sunday to make the country's ailing social security system viable.

"We are voting on an ambitious reform which brings the pensions system of the country onto a viable track," Tsipras said.
