He is tasked with developing a “collective vision” to engage with the public, corporate partners, major donors and trusts to generate a sustainable income.
Clarke will also develop the charity’s global fundraising strategy across Oxfam’s international branches.
Previously global marketing strategy, planning and operations director at Skype, Clarke has also held senior marketing roles at BBC Worldwide, Universal Studios, Disney, and United Biscuits.
Joining on 11 June, Clarke replaces Cathy Ferrier, who left the organisation to join Prince Harry’s development charity Sentebale as CEO in January.
Clarke says: “In these tough economic times it is absolutely crucial that charities find innovative ways to sustain current fundraisers alongside reaching out to new supporters by making the most of every marketing channel possible.
“With the huge increase in new digital and social media networks, and the increasing potential for more collaborative partnerships with corporations, this is an exciting time for fundraising.”
