Liz Whiston, one of the founders of the HHCL Brasserie, is to join St Luke's as a senior copywriter.
She will partner art director Jules Chalkley, one of the agency's four creative directors, under Al Young and Kate Stanners.
Whiston joined HHCL in 1989, one year after the agency's launch, and remained for eight years. In 1985, after two years as creative director, she left to co-found The Brasserie with three other HHCL staffers, sharing the title of creative director with Dave Shelton.
Whiston left The Brasserie last April and has been working on various projects since then, and at St Luke's is working on campaigns for BT, the COI and AMP, the Australian finance house which St Luke's won earlier in the year.
Whiston is best known for the AA 'fourth emergency service' campaign, the Ronseal 'does exactly what it says on the tin' work, the Harry Enfield Cholmenly Warner campaign for Mercury Telecommunications and the Malcolm MacDowell Lineone campaign.
