Vodafone Group Plc (LSE:VOD) is reportedly weighing a potential merger of its Indian arm Vodafone India Limited with rivals as it seeks a turnaround in India mobile market. Vodafone Group's board is now understood to be looking at the possibility of a tie-up with either Reliance Jio Infocomm Limited (Jio), or Idea Cellular Limited (NSEI:IDEA) (Idea), another of the top four providers. Jio and Idea could themselves combine, however.
