Agnès Riousse joins SEC Newgate as Director

SEC Newgate has strengthened its senior UK team with the appointment of Agnès Riousse as Director. Her arrival follows the recent senior appointments of Kate Moffat, Matthew Jervois and Noémie de Andia, marking another significant step in the firm’s continued growth.

Agnès, who was previously a Director at CDR (Citigate Dewe Rogerson), brings 20 years of experience in financial and corporate communications, having advised private and publicly listed companies operating in the UK and globally. She has worked with organisations of all sizes in sectors including consumer, hospitality, financial services, private equity, transport, engineering, telecoms and legal services, guiding them on both ongoing strategic communications and high‑stakes situations.

Her experience includes supporting British and international businesses to articulate their strategies effectively for UK audiences. Agnès is recognised for her expertise in helping non‑UK international players build a meaningful presence, navigate the UK media landscape and secure their fair share of voice in competitive markets.

As the corporate affairs and reputation landscape becomes increasingly complex, her appointment further strengthens SEC Newgate’s ability to guide clients through fast‑moving and high‑stakes environments. 

Alistair Kellie, Practice Head, Communications at SEC Newgate UK, said:

“We’re thrilled to welcome Agnès to the team. She is a highly respected adviser with a long track record of building trusted relationships with senior leadership teams. Her appointment further enhances our ability to support clients across complex corporate and financial communications, and she adds real strength to our growing international offer.”

Agnès Riousse, Director, added:

“I’m delighted to be joining such a dynamic, ambitious and award‑winning team at SEC Newgate. The firm is home to exceptionally high‑calibre advisers, and its integrated model presents huge opportunities for clients looking to communicate with clarity and impact. I’m excited to contribute to the next chapter of the business’s growth.”
