Ben Bramhall, co-chief executive of Xafinity, said: "We have a very clear strategy to continue investing in our people and the services we provide to clients, including de-risking solutions.

“At the same time, we will continue to develop our highly accredited master trust, the National Pension Trust, as we believe this is a solution that employers need in the new world of flexible pensions.”

Paul Cuff, co-chief executive of Xafinity, said: "The IPO is the logical next step in our strategy, enhancing our public profile and status with existing and potential clients and providing access to the capital markets to aid future growth if required.

“We are very pleased with the response of investors to the Offer and thank them for the interest they have shown in Xafinity. We welcome our new shareholders and look forward to working with them to deliver value for all our stakeholders in the business."
