“I’ve had such a rewarding 40 years in journalism. It’s been a fascinating journey and the camaraderie I have enjoyed has been every bit as important as the buzz and excitement of news coverage,” he said.

‘’I am very excited to be moving into a new phase in which I know the experience I have been lucky enough to gain working in the industry will be absolutely invaluable. I find it hard to believe it has been 40 years and while I know that the time is right for me to move on, I will greatly miss working with all my friends and colleagues at wonderful Trinity Mirror titles.

‘’The last few years have seen some of the most remarkable change in media history and it has been terrific to be at the heart of so much innovation and creativity.’’
