In the mid-term legislative election in October 2013，the ruling Frente para la Victoria coalition won a majority of Congress seats. Opposition parties also took advantage of the opportunity to win more seats to increase their influence in the Congress. The economic situation was still grim. There were a variety of macro-economic problems to be resolved，including high inflation，rapid depreciation of exchange rate，the rundown of foreign-exchange reserves and large current-account deficit. Frequent demonstrations and strikes posed a threat to social stability. There was an outbreak of large-scale looting at the end of 2013 as mobs took advantage of the police strike. Argentina’s relations with Uruguay were strained due to disputes over trade and the paper mill by the border.
