Dutch telecoms group KPN announced on July 23, 2013 that will sell its German unit to Telefonica Deutschland O2 for some 8.1 billion euros ($11 billion) in cash and shares, in a long-awaited deal that will test regulators' views in Europe's largest mobile market. If KPN's disposal of E-Plus is finalised, the new company would hold a share of about 30 percent of Germany's mobile service revenue and would be better armed to take on Deutsche Telekom and Vodafone, with 35 percent each.
