’His appointment is part of a new phase for MSI in the UK,’ says managing executive officer

Mitsui Sumitomo Insurance Company has hired a new interim top boss for its UK arm as it announced the subsidary would be rebranding.

The division, which had been called MSI EU, will now be known as MSIG UK and will be temporarily led by Martyn Rodden.

The Japanese insurer said the change ensured alignment with many of the other MSI companies in the global carrier’s international network.

In his new role, Rodden will report into Hironori Morimoto, MSI’s managing executive officer in the UK.

”Martyn’s appointment is part of a new phase for MSI in the UK,” Morimoto said.

“We are reshaping a business that has predominantly focused 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.”


Rodden brings more than two decades of specialty London market experience to the role, including over a decade in executive leadership.

For example, he has worked as chief risk officer at Faraday Underwriting, as well as head of risk at Chaucer’s syndicate business.

He also spent eight years with MS Amlin – Mitsui Sumitomo took over Amlin in 2016 in a £3.5bn deal.

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

“I am delighted to announce Martyn’s appointment as interim chief executive of the newly rebranded MSIG UK.”
