Former Austrian Vice Chancellor and Foreign Minister Alois Mock recently celebrated his 80th birthday on June 10th. Among the well-wishers for the politician was Prince Nikolaus. Both he and Mr Mock are part of the presidential board of the European Society Coudenhove-Kalergi, an association based on the Pan-European idea. It was during Mock's tenure as Foreign Minister that Austria entered the European Union.
