Modern pentathlon From Norman Fox Moscow, July 21 Britain's hopes of recovering from a disappointing opening day's riding in thie modern pentathlon were extinguished here yesterday when the fencing programme left them 938 points behind the Hungarian leaders. T,he manager of the team. Michael Proudfoot, had to admit: "We have con- ceded our title as Olympic champions." Although the British made an astonishing recovery to win the gold medal on the last day in Montreal, they would need to be assisted by almost unprecedented misfortune for the Hungarians, Russians and Swedes to take a place in the top three In these Olympics. Having fallen 262 points behind on the first day, they needed all three members of the team to score higher than 800 points in the fencing. But today not even Danny Nightingale, the Spartakiad champion a year ago, could approach his best form, and he wvas Involved in one particularly bad-tempered bout. He Is now 33rd overall wvith Peter Whiteside ahead of himn in 24th place and Nigel Clark 35th. The competition Is led bv four Eastern Europeans, with a Russian, Anatoly Starostin, trying to overcome the shame of Montreal, when Boris Onischenko was disqualified for tampering with the equipment in the fencing competition. Starosin is 58 points behind Tamas Szombathelyi, of Hungary. Starostin Is the world junior champion but he has in support the Russian veteran Pavel Lednev, four times a wvorld champion and nol; fourth. Lednev is not expected to stay In touch in the swimming and running events. Modern pentathlon British concede their title after fencing
