Flagstone Reinsurance Holdings Ltd. has announced that Dominic Kirby will replace Tom Bolt as managing director of Marlborough Underwriting Agency Ltd. in the autumn.

Mr. Kirby has worked for Flagstone since July 2007, most recently overseeing the marine and energy business and also serving as deputy managing director of Marlborough, where he was instrumental in the integration of Marlborough into Flagstone.

Prior to joining Flagstone, he served as chief underwriting officer for global marine and energy at Navigators Group.

Mr. Kirby will oversee the underwriting operations at Marlborough, working alongside the existing senior management team. Mr. Bolt will leave Marlborough in August to take over the role of underwriting performance director at Lloyds.

Mark Byrne, chairman of Flagstone, said: "We are very pleased to have Dominic move into this new role. His experience at Lloyd's and track-record in the market are first rate, and his promotion positions Marlborough to move forward in a seamless fashion.

"There is great depth in the management team at Marlborough, and they have our full confidence. I would also like to wish Tom the best of luck in his new position at Lloyds and thank him for his successful integration of Marlborough into the Flagstone Group."
