Punch boss Giles Thorley has taken up the post of non-executive group chairman at Cafe Rouge operator Tragus.
Thorley is allowed to hold two non-executive positions and the new job is expected to replace his non-executive position at health and fitness chain Esporta.
The Punch boss insisted the new position was not an indication that he is preparing to leave Punch in the near future.
He said: "I love the business and there is plenty going on at the moment. I've always said I'm not going to (run Punch) for ever but this is not part of an exit plan."
Tragus is working with its advisor Close Brothers on a strategic review of its options which include a possible flotation.
Graham Turner, the former boss of Unique Pub Company who now runs Tragus, said: "His considerable experience across many areas of the leisure sector along with his extensive corporate development experience will provide us with unrivalled expertise and counsel."
Thorley said: "I have watched the development of Tragus with interest and I'm delighted to be joining the group further.
The success of the core Cafe Rouge and Bella Italia brands and the recent launch of Ortega mean I am joining at a very exciting time - with plenty of further opportunity ahead."
