Mike has decided to step back from his director’s role at GMX and will be leaving with immediate effect.

Commenting on the news, Dean Weller, chief executive of Generation Media, said: “Mike has been a well-respected and important member of the team, and has contributed enormously not only to the successful development of GMX, but also to improving the media buying and planning performance on those clients that he has worked on. Currently Mike is bravely fighting serious illness and everyone in the group wishes him and his family well in this regard.”

Whilst Mike will not be continuing in front-line media duties, he will continue to be involved in the toy and retail business as he pursues new opportunities outside that of media planning and buying.

Dean added: “Mike will always be welcome at Generation Media Group, and of course we all wish him the best for the future.”
