On his apprenticeship, he earned £300 a week working a 60-hour week plus 10 hours' overtime on Saturdays, while also attending classroom-based training at college on a day release basis.

Spellman shot some additional test material of Martin back at home in the summer and the boss of North One television showed the clips to a BBC executive.
Having engaged Andy Spellman as his advisor and agent in 2009, Martin worked with North One TV Producers James Woodroffe and Ewan Keil, as he has done to present day.
His mother, Rita Kidals, was of Latvian heritage, her father having come to Britain in 1947 as a political refugee.

In the search for a more competitive team, Martin joined Hydrex Honda for the 2007 season.
