Richard Mully joined the GPE Board in December 2016 and has been appointed as Chairman following a selection process led by GPE's Senior Independent Director, Charles Philipps which involved consideration of candidates with the assistance of a leading search consultancy.

Following 12 years of banking experience focussed on property with County Bank and Bankers Trust, Richard spent 13 years as a principal real estate investor with Soros Real Estate Partners and Grove International.

Martin Scicluna said, "I am delighted that Richard has been selected to succeed me as Chairman and I wish him and the Company every success. It has been a privilege to serve on GPE's Board for the past ten years and I have thoroughly enjoyed working with Toby Courtauld and the GPE team. The Company is in great shape with its robust financial position enabling management to continue to capitalise on both internal and market opportunities".

Richard Mully said, "With management's strong track record, the quality of the portfolio and potential of the development pipeline, I look forward to working with the GPE team. On behalf of the Board, I would like to thank Martin for his valued contribution and stewardship over the past ten years. His wise counsel and collegiate approach both in and outside the Board room will be missed."
