A referendum has been held in Switzerland on whether Swiss neutrality should be more strictly enforced in the Constitution. Richard Werly, Europe correspondent for the Swiss publication Blick, tell us why the Swiss have voted "no".
It was at the Congress of Vienna in 1815 that Swiss neutrality was internationally recognised. After the defeat of Napoleon, European powers wanted a stable buffer as the balance of power was being reconstructed. There were no camera phones back then; it is the work of the great French artist Jean-Baptiste Isabey that captured the meeting.
