Graeme Murray Walker, OBE is a semi-retired Formula One motorsport commentator and journalist. For most of his career he worked for the BBC, but when it lost the contract for F1 coverage to the company ITV, Walker continued his commentating after the change of broadcaster.
He has a distinctive, enthusiastic commentary style. Since 1978, British television commentary of the Formula 1 seasons has been used by other broadcasters right around the world, including Australia and Japan. He was an exponent of the commentator's curse, noting in an interview that he might say how well a driver was racing or that they would probably win the race, only to have them retire or crash out of the race shortly thereafter, hence his catchphrase "...Unless I'm very much mistaken..." which might lead shortly after to a correction "...And I am very much mistaken...".
He is known for his gentlemanly and considerate conduct, seeing the best in drivers who had attracted controversy. He rarely criticised drivers and preferred to give the benefit of the doubt in attributing blame for incidents. One example of this was during the 1994 Australian Grand Prix where, following the controversial crash between Michael Schumacher and Walker's close friend Damon Hill which decided the World Drivers' Championship in the German's favor, Walker, unlike his fellow commentators at the time, most notably former 500cc Motorcycle World Champion Barry Sheene, declined to blame Schumacher outright for the crash.
