One of the major deals of the last week was the move by Li Ka-Shing, the richest man in Hong Kong, to purchase a British unit of the French power giant Electricite de France for a shade over $9.1 billion. Herbert Smith and DLA Piper scored lead roles in the deal, through which companies controlled by Li will take control of a power grid that supplies London, the London Underground and Heathrow and Gatwick airports, according to the U.K. publication Legal Week.

DLA Piper advised Cheung Kong Infrastructure, the lead partner in a consortium of Li-controlled companies that will take over the power grid as part of Li’s continued push to expand beyond Hong Kong, according to Legal Week and The Wall Street Journal.
