Martyn Rodden Appointed as Interim Chief Executive Officer of newly rebranded MSIG UK


New executive marks the next chapter in MSI’s growth story


LONDON, 8 February 2024. Mitsui Sumitomo Insurance Company (Europe), Limited (MSI EU), the UK subsidiary of Japanese insurer Mitsui Sumitomo Insurance (MSI), today announces the appointment of Martyn Rodden as Interim Chief Executive Officer (CEO) effective immediately, subject to regulatory approval. Rodden, previously Director of Strategy & Transformation at sister company MS Amlin Underwriting Limited (MS AUL), will report into MSI’s Managing Executive Officer in the UK, Hironori Morimoto.


Martyn Rodden brings more than two decades of specialty London Market experience to the role, including over ten years in executive leadership. As a member of the Executive Committee at MS AUL, he played a vital role in developing and implementing a change in strategy that has seen the firm’s fortunes reverse over recent years. This included leading the delivery of the successful Reinsurance To Close deal in 2023, one of the largest deals of its type in Lloyd’s history.


Prior to his new role at MSI EU, Rodden spent eight years at MS Amlin, in increasingly senior roles. With a career spanning many significant London Market brands, he was previously Chief Risk Officer at Faraday Underwriting, as well as Head of Risk at Chaucer’s syndicate business.


Simultaneously, MSI EU confirms it will be changing its trading name to MSIG UK. This change ensures alignment with many of the other MSI companies in the global carrier’s international network, and comes after MSI celebrated its centenary in the UK insurance sector, earlier this week.

Martyn has shown fantastic commitment and leadership at MS Amlin, to help return the business to profitability and become a £2bn syndicate, once again.


Martyn’s appointment is part of a new phase for MSI in the UK, reshaping a business that has predominantly focussed on supporting Japanese clients, as part of MSI’s ambitious international growth plans. The MSI network of companies provides Martyn and the team with significant opportunities to grow the business, including working with sister firms such as MS Amlin, to help develop and deliver new solutions for clients, as well as building our existing UK portfolio.”
