"After a great deal of careful thought, I have decided to move on from McLaren, a company I have loved and served for 10 sometimes wonderful but occasionally difficult years," said Bishop. "It was a tough decision, but it was the right one: the time is right.
"Being offered a McLaren job in the autumn of 2007 was a dream come true for me – and, although the past 10 years have been characterized by a huge amount of extremely hard work, I have enjoyed them enormously.
"I have had the privilege of working with a large number of truly exceptional people, including three world champions [Lewis Hamilton, Jenson Button and Fernando Alonso], and I am indebted to all my colleagues, past and present, for the inspiration and support they have given me throughout my time at Woking. I wish them every success in the future.
"But, as I say, the time is right, now, for me to move on from McLaren. The recent changes in the ownership and leadership of Formula 1 have made it an even more exciting business in which to work, and, desirous as I am to broaden my professional outlook on the sport I love, I intend to pause, reflect and take stock, before examining what exciting new challenges I may be able to take on."
"Matt's contribution to the development and improvement of McLaren's communications, PR and digital/social media offerings has been enormous," said Zak Brown.
"He's a good guy, and will be missed," Brown continued. "But I always respect ambition, and recognize that Matt's opportunities in Formula 1 are many and varied. Given the exciting changes in our sport, I can understand his desire to pursue such opportunities, and to that end I, and all at McLaren, wish him well."
