BERLIN (Reuters) - Germany's federal cartel office on Tuesday launched an investigation into the German football association's (DFB) sale of tickets for the national team's matches at Euro 2016.

German fans wanting to watch their side in the tournament in France must first be members of the official fan club before purchasing tickets, hiking up their cost by an additional 40 euros (£32).
