Stan Kott, CEO of Wellington Underwriting's US operations has become the latest senior figure to leave the company just weeks after its merger with fellow Lloyd's insurer, Catlin.
Kott handed in his resignation this week hot on the heels of other high-profile departures including chairman, John Barton and a number of senior underwriters.
The news of Kott's resignation is not expected to help Catlin's ambition of being a global insurer, which is said to depend upon it building a significant US presence, an area where Wellington already has a well established presence.
Since the company's £600m takeover by Catlin a number of underwriters have left Wellington, including Robert Swinton and Noel Holloway, the head and deputy head of Wellington's aviation team, who left the company early last week.
Other departures include hull underwriter Peter McIntosh, and bloodstock/livestock underwriter, Alex Colquhoun, as well as the insurer's four strong UK property team headed by Mike Platt, who resigned to go to Novae Group.
Meanwhile Wellington's former group head of risk, David Gittings, left to become chief executive of the Lloyd's Market Association with Wellington non-executive directors John Engestrom, Paul Hamilton and Julian Hance, also deciding to leave.
