The scenes in Berlin tonight are impressive and evocative, as world leaders gathered to mark 20 years since the dramatic night that the wall began to come down. It was particularly poignant to see former Soviet President Mikhail Gorbachev taking part in the commemorations, 22 years after President Reagan's famous speech calling on him 'Mr Gorbachev, tear down this wall'. In the event, it was the people of Berlin themselves who tore it down.It seems now almost literally unbelievable that in our recent history an armed frontier divided a major European City marking a global contest between democracy and communism. Many people have offered their reflections today, far more eloquently than I can manage. David Cameron and Margaret Thatcher have both given their thoughts, but I give the last word to German Chanceller Merkel, herself from East Germany:
'Today marks a truly happy moment of German and European history. Twenty years ago the door to freedom opened up and a seemingly invincible wall that divided a people and an entire continent suddenly became permeable. It was one of the happiest moments of my life. '
