Leading German cable operator Kabel Deutschland is planning a nationwide TV platform after agreeing to buy three regional rivals.

The group -- owned by three US investment companies, Goldman Sachs, Apax Partners and Providence Equity Partners -- has agreed to pay around €2.7 billion ($3.3bn; £1.8bn) for Ish, KabelBW and iesy. All four companies were created by the auction of Deutsche Telekom's cable assets over the last four years.

If the deals gain regulatory approval, they will give Kabel Deutschland a pan-German presence. The company then plans to invest €500m over three years as it launches digital television services.
