HARDtalk - Diego Arria, Former Venezuelan Ambassador to the UN

Interviews with newsmakers and personalities from across the globe. Last month the Venezuelan opposition made a dent in President Hugo Chavez's popularity when they increased their share of the vote in the National Assembly elections. The opposition coalition claimed almost half the vote and now has enough seats to exercise some blocking power. Diego Arria is a former Governor of Caracas and was Venezuela's Permanent Representative to the UN in the early 1990s. Now he is a vocal critic of President Chavez. Does he and his allies have what it takes to roll back Venezuela's socialist revolution? Diego Arria talks to Stephen Sackur.
