As director of Campaign for the Arts, Gamble has continued to work tirelessly to carry out the organisation’s mission of championing, defending and expanding access to arts and culture. Listed in The Stage 100 for the third year in a row, one of the organisation’s biggest campaigns of 2025 was a petition ahead of Rachel Reeves’ spending review calling for sustained funding for the arts, which received more than 37,000 signatures across every parliamentary constituency in the UK.
