DLA Piper has taken the lead role for Qatar-based news network Al Jazeera on its acquisition of former US vice president Al Gore’s cable television channel Current TV.

The US-based news channel was co-founded by Gore (pictured) and and former Paul Weiss Rifkind Wharton & Garrison lawyer Joel Hyatt. The value of the deal was undisclosed, but is widely estimated to be worth around $500m (£309m).
