Outgoing Deutsche Bundesbank (German Federal Bank) boss Axel Weber has enjoyed a night at the opera as rumours about what he might be getting up to next are flying.The banker surprisingly announced his resignation as head of the Deutsche Bundesbank as of 1 May. Weber was previously thought to be in with a good chance of succeeding Jean-Claude Trichet as chief of the European Central Bank (ECB). Weber has remained tight-lipped on his future plans. Rumour has it he could join the Deutsche Bank board.Weber and Austrian National Bank (OeNB) President Ewald Nowotny watched Wolfgang Amadeus Mozarts opera “Le nozze di Figaro” (The Marriage of Figaro) at the State Opera in Vienna on Saturday. The bankers were spotted dining at Hotel Sacher afterwards.The sold-out opera production starring Uruguayan bass-baritone Erwin Schrott was also attended by TV presenter Barbara Rett and former Austrian Peoples Party (ÖVP) Chancellor Wolfgang Schüssel.
