TOPSHOTS Members of the Communist Party-affiliated trade union PAME shout slogans during a demonstration against the fresh austerity measures, in Athens on July 22, 2015. Prime Minister Alexis Tsipras faced a new test of his authority in parliament on July 22, where MPs were to vote on a second batch of reforms to help unlock a bailout for Greece's stricken economy. The embattled premier last week faced a revolt by a fifth of the lawmakers in his radical-left Syriza party over changes to taxes, pensions and labour rules demanded by EU-IMF creditors.
