Stewart held the record for most wins by a Formula One driver (27) for 14 years until Alain Prost won the 1987 Portuguese Grand Prix, and the record for most wins by a British Formula One driver for 19 years until Nigel Mansell won the 1992 British Grand Prix. In his commentary work for race broadcaster Channel 9 during qualifying for the 1988 Australian Grand Prix, Stewart said that he had been asked numerous times if he was unhappy about losing his record to Prost, going on to say that he was happy that his record had been taken by someone of the calibre of Prost, as he believed him to be the best driver in Formula One.
