FRANKFURT, May 9 (Reuters) - Telefonica Deutschland , Germany's third-largest mobile operator, said Vodafone's proposed $21.7 billion takeover of Liberty Global's European assets would lead to excessive market concentration.
"It's clear that the announced transaction would create a monopoly in cable content distribution and a de facto duopoly in fixed-line infrastructure in Germany," Chief Executive Markus Haas said in a statement.
"We therefore expect close scrutiny from the responsible competition authorities. If this combination is in any way approvable, then only under appropriately strict conditions."
Telefonica Deutschland, majority-owned by Telefonica of Spain, has a mobile-led strategy. That leaves it vulnerable to 'converged' mobile and fixed services offered nationwide by market leader Deutsche Telekom and, if the proposed deal goes through, Vodafone.
