Portland Communications is one of the United Kingdom's leading international public affairs and strategic communications consultancies and one of the most internationally built public affairs firms operating globally. Founded in London in 2001 by Tim Allan — former deputy press secretary to UK Prime Minister Tony Blair and former Director of Communications at BSkyB — the firm was acquired by Omnicom Group in April 2012 for approximately £20 million via Omnicom's Diversified Agency Services division. Mark Flanagan has served as Chief Executive Officer since January 2020. The firm operates from London (headquarters), Washington, D.C., Doha, Nairobi, Singapore, Brussels, Paris, Berlin, and New York with approximately 490 employees. Portland was confirmed as unaffected by the February 2026 Omnicom Public Relations Group restructuring that consolidated Golin and Ketchum and folded Porter Novelli into FleishmanHillard.
The Founder and the Founding Era
Tim Allan founded Portland in 2001 in London. Allan served as deputy press secretary to UK Prime Minister Tony Blair under Communications Director Alastair Campbell from 1995 to 1998, then as Director of Communications at BSkyB from 1998 to 2001. The firm launched on the back of a foundational contract from BSkyB Chief Executive Officer Tony Ball, who had previously been Allan's boss. The founding orientation was New Labour-aligned. Across the 2000s and 2010s the firm built cross-party credentials and expanded into Conservative and Liberal Democrat insider work, becoming one of the dominant UK public affairs consultancies.
The 2012 Omnicom Acquisition and the 2019 Gplus Merger
In April 2012, Omnicom Group acquired a majority stake in Portland for approximately £20 million via Diversified Agency Services. The transaction preserved operational independence under Allan while integrating Portland into the Omnicom portfolio. Portland continued expanding internationally — opening offices in Washington, D.C., Doha, Nairobi, Singapore, and other key markets. In November 2019, Omnicom merged Portland with Gplus, Omnicom's Brussels-based European political and communications firm, strengthening Portland's continental European footprint. Allan announced his departure at year-end 2019. Mark Flanagan — then Portland's managing director and a former head of strategic communications at 10 Downing Street under both Labour and Coalition governments — succeeded him as Chief Executive Officer in January 2020.
The Allan-to-Downing-Street Sequence
In July 2024, Tim Allan was appointed Director of Communications at 10 Downing Street under Prime Minister Keir Starmer. He served in the role for less than six months before resigning on February 9, 2026 — one day after the departure of Starmer's Chief of Staff Morgan McSweeney — to allow Starmer to build a new public-relations team. Allan retains a minority stake in Strand Partners, the separate UK public-affairs consultancy whose clients include Netflix, the British Horseracing Authority, and Cadent Gas.
