Morgan Stanley is Financial News's investment bank of the week after advising Germany’s largest cable company, Kabel Deutschland, on a €600m acquisition of a domestic rival. It is the US bank’s first mandate from Kabel Deutschland since it helped the group go public two years ago.

Kabel Deutschland announced on Monday that it had agreed to buy Tele Columbus for €603m, plus accrued interest, equivalent to €618m. Berlin-based Tele Columbus provides basic cable services to around 1.7 million customers, predominantly in Berlin and east Germany. As a result of the deal, Kabel Deutschland's direct subscriber base will be increased to 8.9 million.
