The honour has been given to Milsom in recognition of his contribution to the brand over the years.
His late father, Gerald Milsom, founded the group back in 1982. He remained life president until his death in 2005, when the title passed to George Goring, from The Goring.
Kalindi Juneja, chief executive, said: “I am absolutely delighted that Paul Milsom is Pride of Britain Hotels’ new life president. His enduring commitment to the organisation and to UK hospitality is highly appreciated.
“Paul is a hotelier I deeply admire; his business acumen and industry knowledge have been invaluable to me as I stepped into the role of chief executive last year. He is always available to help the team or any member hotelier; we are very lucky to have him.”
Milsom added: “I have always believed in the power of the Pride of Britain Hotels consortium and the support it provides to UK hotels.
“Under Kalindi’s leadership, we are embarking on a new chapter for our brand and I look forward to my many more years of service.”
