Citypink, one of Europe’s largest networks for gay professional women, holds its 2010 summer party on the roof terrace of London’s swish Chelsea Harbour Club on July 31.

Along with the barbecue and copious champagne, there’ll be a lovely (but as yet top secret) celebrity handing out the prizes, entertainment from DJs Benji de la House and Lady Alexandra T. (fresh from Paris and their residencies at the famous Primanotte parties), and a fabulous charity prize draw courtesy of Breitling.
