The previous Syriza/Anel government collapsed, due to a split in Syriza last month.
As result, the party's leader and Prime Minister Alexis Tsipras was forced to call snap elections.
About 25 rebel Syriza MPs, who objected to Mr Tsipras's acceptance of more austerity demanded by Greece's creditors, formed the Popular Unity party, challenging Tsipras and Syriza. (BBC)
