[Region], June 2009 - Biz Stone, co-founder of Twitter, www.twitter.com will lead Hill & Knowlton's seminar in the first ever 'Official Cannes Lions Tweet-Up' at this year's festival. H&K is the only PR agency to secure a seminar slot during the week-long programme of events, and Biz Stone will lead the session taking place on Monday 22nd June at 4pm. Biz will be speaking about life, the Twitterverse and everything in between, before taking questions live on Twitter.

Biz Stone, co-founder of Twitter commented: "I'm flattered to be a guest speaker at Cannes Lions this year and look forward to fostering new ideas with the world's top brand marketers, and galvanizing their experience within the community."

Tony Burgess-Webb, chief marketing officer at Hill & Knowlton said: "It's great to have Biz leading our inaugural seminar at Cannes. Twitter is without doubt the hottest communications platform in the world right now and is leading a massive change in the way people engage with each other and with brands. This has profound implications for the public relations industry specifically and for marketing generally".

Two of Hill & Knowlton's global management team will judge at this year's festival, Jimmy Tay, head of H&K South-East Asia and MaryLee Sachs, global head of H&K Marketing Communications and US Chair. Often billed as the 'Oscars of the marketing industry', this is the first year that Cannes Lions, now in its 55th year, has added a PR category, a move which recognises the increasingly crucial role PR plays in brand communications.

H&K is also a sponsor of the MOFILM User-Generated Content "You to the Power of 12- U12" Competition at Cannes Lions. http://www.mofilm.com/
