Yahoo seeks allies to fend off Microsoft and Murdoch

Microsoft's attempt to take over Yahoo is threatening to turn into a "rumble in the jungle", according to one investor, as both sides seek to bolster their positions.

The battle has taken a series of complex twists, with the possibility of the internet's most powerful names lining up on either side. Microsoft is rumoured to be on the verge of a collaboration with News Corporation and Yahoo is hoping for help from AOL and Google.
