By Renee Maltezou and Angeliki Koutantou ATHENS (Reuters) - Greek Prime Minister Alexis Tsipras had less than 48 hours on Tuesday to pass a series of pro-market reforms in parliament and smother dissent from hardliners within his own ranks as he races to meet the terms of an unpopular bailout deal. Having staved off financial meltdown with a new agreement from Greece's international creditors, Tsipras now faces the anger of lawmakers and the public for agreeing to measures much tougher than those rejected in a referendum on July 5. The ruling Syriza party and its junior coalition ally held separate meetings to prepare for parliament sittings to pass the laws, which include plans for tax hikes, pension reforms and tighter supervision of the government's finances.
