Wife Sally was killed, while six-year-old son George survived the crash. He is currently in Southampton General Hospital.

"Lewis and Sally were a hugely popular couple and their tragic and untimely loss will leave a big gap in the lives of the great many people that knew and loved them," wrote Simon Flatt, co-founder, on PMC's blog.

Tonkinson helped launch Birmingham-based PMC, an integrated marketing communications shop geared to tech and life sciences clients, in 1996.

He began his career at Lucas Industries in the engineering design unit before shifting to sales and marketing in its automotive group.

Previously, Tonkinson was at Gould Electronics and Lesniak Jones Liddell (ad/tech PR shop) before starting PMC in 1993.
