OMSK, Siberia - A British female participant in the 2013 Peking-to-Paris 'classic cars' rally has been killed in a head-on collision in western Siberia.Mother-of-two Emma Wilkinson, 46, was sharing a 1970 Chevrolet C10 with partner Peter Davies on Wednesday (June 12) and driving at around 50km/h on the Tyumen-Omsk federal highway when their car and a VW Polo collided. Davies was not hurt.The Polo was occupied by two adults and a baby. A 31-year-old man and the baby died; a woman is in intensive care.'FUN-LOVING AND LIVELY'The Tyumen police are considering a theory that the VW driver fell asleep at the wheel and drifted across the highway into the path of the Chevrolet. There were no skid marks and traffic was very light; Wilkinson was in no hurry as the section she was driving was an easy main road and her target schedule was 50km/h.Rally director Philip Young said: “Emma was a fun-loving, lively and popular member of the rally. In the three weeks we've been together she and Peter proved themselves to be capable, competent and resourceful."Their 1970 Chevrolet C10 pick-up was a remarkable sight in the Mongolian wilderness and today our thoughts and sympathies are with Emma's family and friends, including her brothers Robert and Mark who are also in the event.”The Endurance Rally Association team in Russia and the rally's UK office are working with the local police, the British Foreign Office and the British Embassy to help Wilkinson's family.
