The charity offers both practical care and emotional support for people who are dying, either in their own home or one of its hospices.
Saatchi & Saatchi will now develop all Marie Curie’s above-the-line and digital marketing communications, including the brand’s relaunch under a new positioning in September 2015. Magnus Djaba, the chief executive of Saatchi & Saatchi Fallon Group UK, said: "We are incredibly proud to have the chance to work with an organisation that is extremely close to my heart and to the hearts of many of the people within the agency. We look forward to raising awareness of its work and goals."
Chris Dainty, the director of communications for Marie Curie, said: "Saatchi & Saatchi impressed us with their clear strategic thinking."
The appointment does not affect Marie Curie’s fundraising agency, Bluefrog, or WPN Chameleon, which handles DRTV.
