Lord Archer of Weston-Super-Mare, as we can call him because, unlike Lester's OBE, they are unable to take his title away, gained a place at Brasenose College, Oxford to study for a one-year diploma in education, though he eventually stayed there for three years. This doesn't justify his claim to be an Oxford graduate. He doesn't even have any A levels.
While he was at Oxford he did compete successfully at a decent level in 100 yards and 200 yards sprinting and in the high hurdles. Being Jeffrey, he claimed to have been on the GB Olympic team, which he wasn't, though he may have had trials. He did run against Ming Campbell, who was an Olympic athlete.
But then, among many other things, he once said that his father had been Viceroy of Brunei. Not only was this untrue, but Brunei has never had a Viceroy. Jeffrey's father, William, was a journalist in Weston. Jeffrey was a member of the DCM League, which you can only join of you or a close relitave holds the Distinguished Conduct Medal. When asked, Jeffrey said "I rarely talk about my father and his DCM". Maybe that's because his father didn't win the DCM. A William Archer did, but a completely different William Archer.
Good old Jeffrey - the truth, the whole truth and nothing but the truth.
