Derwent London today announces that Paul Williams has informed the Board of his intention to retire as Chief Executive and Director of the Company.

Paul will remain in his role until his successor is in place at which point he will step down from the Board.

A thorough process to appoint a successor, led by the Chairman Mark Breuer, will commence immediately.

Mark Breuer, Chairman, commented:

"I would like to thank Paul for his dedication and commitment over the last 38 years. During his distinguished career, including his tenure as Chief Executive, he has made an outstanding contribution to Derwent London. With its market leading position, ongoing commitment to capital recycling and significant development pipeline, Derwent London is well placed to create significant value for shareholders."

Paul Williams, Chief Executive, said:

"It has been a huge privilege to have been part of the Derwent story and to have had the opportunity to lead the business over the last six years. I am very proud of what we have achieved, positioning the business with world class assets in prime locations across London, attracting sustained and strong occupational demand. I would like to thank my fellow directors and all the team for their continued hard work and support. I remain fully focused on driving the performance of the business until my successor is in place."
