Two new editors have been unveiled at former Local World dailies now owned by Trinity Mirror.
George replaces Kevin Booth at the Mercury, while David takes over from Paul Brackley.
Both Kevin and Paul’s departures were announced within the space of 24 hours by TM in April.
Manchester Evening News editor Rob Irvine has since been in charge at Leicester on an interim basis.
George, 36, said: “I am proud to have been given the opportunity to edit a newspaper with the history and standing of the Leicester Mercury.
“I’m also very much looking forward to working with my new colleagues to continue the Mercury’s rapid development in digital publishing and audience growth.”
George worked at The Sentinel, Stoke, earlier in his career, and has been described by TM as a “key player in the Gazette achieving one of the highest pages-per-user figures in the regional press”.
Since Kevin’s departure, cuts have been announced to both the Mercury’s photographic and features departments.
“It’s a really exciting time to be joining the Cambridge team and I look forward to helping grow the brands as we increase the focus on audience and digital growth.
“I’d like to thank all my colleagues in Liverpool who have been wonderful to work with for the past nine years. It has been a privilege, and I leave behind many good friends in the newsroom.”
During his time at the Echo David reported on stories including the release of previously unseen documents made public by the Hillsborough Independent Panel.
Prior to joining the Liverpool newsroom in 2007, David worked at the Lancashire Telegraph and the Preston Citizen.
Neil Benson, Trinity Mirror’s editorial director regionals, said: “David and George are two of our brightest talents, who have proved themselves to be equally skilled in the print and digital spheres.
“It is testament to the depth of talent within Trinity Mirror that in each case they came through as the best of an extremely strong field of candidates. I wish them every success in their new roles.”
