History
Euro RSCG London was first created by merging Colman RSCG and Horner Collis Kirvan.

In 1994, Euro RSCG's London office was relaunched as Euro RSCG Wnek Gosper by Mark Wnek and Brett Gosper who had been approached by the Euro RSCG network to turn the agency around. Brett Gosper left for New York in 2003. Mark Wnek also left in January 2004, whereafter the names of the founders were dropped and the agency was renamed Euro RSCG London.

Euro RSCG itself was renamed Havas Worldwide in 2012, and the London office was then renamed Havas Worldwide London. The name was later shortened to Havas London.
