Malcolm and Moore had shared the title of creative director at Faulds and worked across both its London and Edinburgh offices.
The hiring will come as a blow to the aspirations of the Edinburgh-based shop to build the profile of its satellite London office. Since the completion of its management buy-out in December 2001, Faulds chiefs have made no secret of their desire to crack the London market.
Faulds launched its London office in July last year using the acquisition of the creative duo's independent agency, Malcolm Moore Deakin Hutson, to give it a running start. Graham Deakin, the managing partner, and Anna Hutson, the planning director, will remain with Faulds and it will keep its London office running.
Malcolm and Moore, who during their time at TBWA/London created award-winning ads including the Nike "parklife" spot, which won them three D&AD silver Pencils, will join Wieden & Kennedy London as senior creatives working under the joint creative directors, Tony Davidson and Kim Papworth.
The duo will once again get the opportunity to work on the Nike account, a global Wieden & Kennedy client.
W&K has looked to build its creative department following an increase in work from existing clients such as Loot and Honda. It also recently won the multimillion-pound global creative advertising account for the electronics goods brand Aiwa.
Commenting on the loss of the pair, Dennis Chester, the chairman of Faulds, said: "Tony and Guy are on long-term contracts with Faulds. I will be in negotiations with them and we will make our plans after that."
Faulds' main client in London is British Bakeries. In April, the Scottish office lost the £4 million creative ad account for the car-repair company Kwik-Fit to BMP DDB.
Malcolm and Moore began their 18-year partnership at Leagas Delaney.
Their career includes stints at Simons Palmer Denton Clemmow and Johnson, CDP and Abbott Mead Vickers BBDO.
