Macfarlanes, Travers Smith and Latham & Watkins have scooped the lead roles on the sale of media intelligence website Gorkana to the owner of rival PR software provider Cision in a deal valued at up to £200m.

Gorkana, best known for its extensive database of media professionals, has been sold by its owner, British private equity firm Exponent, to US rival GTCR, which is bolting on Gorkana to its existing Cision brand as part of an expansion strategy which also saw GTCR recently acquire Vocus, another piece of software for the PR industry.
