The Fall of the Wall 8.00pm BBC2
It is hard to believe that just five years ago the whole of Eastern Europe was governed by communist regimes. With the fall of the Berlin Wall in November 1989 all that changed, and within two years all those communist regimes had gone.
The first of two documentaries, A Hole in the Fence reveals the diplomatic intrigues that led to the I wall's demise. In 1987 the East German government was in a state of euphoria after its president Erich Honecker was ceremonially greeted in the West German capital of Bonn. To the East German regime this signified an acknowledgement of its permanence. But the government in Bonn had other ideas and with help from the United States was trying to undermine East Germany and its fellow communist states. Government leaders and the people on the ground who implemented official policies talk candidly about this tense time. Part 2, The Fatal Error, is shown next Sunday.
