A wave of austerity measures proposed by the Portuguese government have won the approval of the country\'s EU-IMF creditors, Deputy Prime Minister Paulo Portas said on Thursday, though a request to ease deficit goals was refused. Lisbon had lodged a request to raise its 2014 deficit target to 4.5 percent of national output but \"the troika did not come back on its position and will only accept 4 percent\" as previously agreed, Portas said.
