Vodafone Group's £15 billion ($19.1 billion) merger with Three won the UK’s antitrust watchdog’s approval, paving the way to create Britain’s largest telecommunications operator by revenue. The two companies have committed to invest £11 billion in the UK’s digital infrastructure to win approval for the deal.

Vodafone Group CEO, Margherita Della Valle, tells Bloomberg's Tom Mackenzie what the deal means for prices, headcount and future consolidation across the European telecoms sector.
