North P&I Club has finally completed the integration of the Sunderland Marine Insurance’s business into its parent company, North P&I Club.

Although the cities of Newcastle — the base of North P&I — and Sunderland are fierce historic, economic and sporting rivals, the two marine insurance providers are now fully joined up as one.

The formal transfer of business will be completed at the end of Tuesday and comes six years after North P&I and Sunderland Marine started to merge their interests.
