Campaign's website spotted BBC News Director James Harding relaxing at a PR Christmas party last week. Robert Peston was apparently also there.
The event was held in Mark's Club, Charles Street, Mayfair and may represent the first sighting of a pullover in this private members' establishment. Dress code: "Ladies should be elegantly dressed and gentlemen are required to wear a jacket and collared shirt at all times. Whilst suits are actively encouraged, in recognition of evolving style, chinos and smart, dark jeans will be permitted. Trainers and sportswear are not permitted."
