Countdown (game show)
Over time, the additional hostesses on the programme were dropped by production staff but retained Vorderman and assigned her primarily to handle the selection of letter and number tiles, as well as verifying contestant calculations. Thus her role was expanded to that of a co-presenter alongside Whiteley in 1989. The programme frequently rotated between various lexicographers, including Richard Samson and Alison Heard, for each series, until in 2003 the role was permanently given to Susie Dent, after her debut on Countdown in 1992.
