Lawrence Graham played a starring role behind the scenes as Leona scooped victory in the X-Factor final.
The firm advised the show’s voting services provider, Harvest Media Group, on an $8m (£4.1m) investment by discretionary funds managed by FF&P Private Equity, the private equity division of Fleming Family & Partners.
Lawrence Graham corporate partner Hugh Maule commented: "Lawrence Graham is very pleased that our lawyers managed to make enough calls to swing the telephone voting to secure our appointment as Harvest's lawyers."
FF&P invested $8m into Harvest Media Group, giving the group full control of Telescope, a leader in mobile services and participation television in North America. Telescope Inc has the largest phone voting system in the world and handled more than 550 million votes for the most recent series of American Idol.
Maule worked on the deal with the assistance of solicitors Geoff Gouriet and Marc Wilshaw.
Kirkpatrick & Lockhart Nicholson Graham acted for FF&P Private Equity.
Formed in 2004, Harvest designs and implements interactive services for broadcasters utilising the telephone, interactive TV and the internet.
