NP, the Golley Slater owned public relations agency, will begin working on three national consumer PR accounts this month.
Weight Watchers has appointed the firm to work on its Walkers Shortbread business following a pitch.
NP already works on a number of Weight Watchers products direct for clients such as Kavli and Richmond Icecream, however, the latest appointment marks the first time NP has worked with Weight Watchers directly.
According to industry sources, other new business wins for the agency are thought to include The Horror Channel and Brasher.
The Horror Channel, the digital TV station dedicated to showing horror movies, is believed to have tasked NP with a number of PR activities.
Completing the hat trick is the outdoor-shoe brand, Brasher, which is understood to have appointed NP to the £70,000 account after short-listing the agency from an initial ten firms.
