Based in Manchester, Nagra’s appointment establishes a senior claims presence at the heart of BHSI’s UK National team, reinforcing a commitment to the city and to the national business.

Nagra comes to BHSI with more than two decades of claims management experience. Most recently, she was UK Motor Claims Manager at AIG, where her career also included leadership roles handling casualty and disease claims.


Bermuda-based Mosaic Insurance has announced five recent underwriting appointments to its political risk, professional liability and financial institutions units.

Finn McGuirk

Finn McGuirk, an experienced Lloyd’s of London specialty underwriter, has been appointed senior vice president, head of Political Risk. He is responsible for building this fast-evolving class of business—one of seven lines the new insurer will underwrite globally through its Lloyd’s Syndicate 1609.

McGuirk has nearly 25 years of experience in the political risk market, initially as a broker before moving to underwriting. Most recently, he was head of the political risk and trade credit accounts for Pembroke Syndicate 4000 at Lloyd’s and headed similar divisions at AXA ASR and CNA Hardy. Previously, he worked for Chaucer Syndicates and Berry Palmer & Lyle.

Anna Jay

Mosaic also recently appointed Anna Jay and Christopher Webb to its London underwriting team. Jay has been named SVP, head of Professional Liability. She has 18 years’ experience working across the specialty sector with a core focus on this product line.

Jay’s career in the London market began as a specialist-placing broker, before she moved to underwriting, spending a decade at QBE International. She later joined Pembroke Syndicate 4000 at Lloyd’s in 2016 and served as divisional director of professional lines for the syndicate.

Christopher Webb

Webb joins Mosaic as SVP, underwriter, Financial Institutions, reporting to Chris Brown. He has nearly 40 years’ experience in the Lloyd’s market, first as a financial institutions placing broker, and later as an underwriter in the sector. He has spent the last 13 years as a senior underwriter for Syndicate 4000.

Danny Clack, a nearly 20-year veteran of Lloyd’s of London and the commercial insurance market, last month was named SVP, deputy active underwriter, at Mosaic.

Clack has joined the London team and supports Active Underwriter Charlie Mackey across all business lines through Mosaic Syndicate 1609, with a focus on professional liability underwriting.

Clack has 15 years of underwriting experience at Lloyd’s, including serving as deputy active underwriter and head of professional lines for Syndicate 4000, which he joined in 2006 to underwrite professional indemnity insurance. Previously, he underwrote environmental insurance in the London market.
