A British survivor of a Himalayan storm which killed at least 29 people, says "poor policy, poor systems and poor leadership" were to blame for the tragedy. Paul Sherridan, a police officer from South Yorkshire was among more than 200 trekkers caught in blizzards and avalanches in Nepal's Annapurna range. Rescuers are continuing their search for survivors. Paul spoke to Anna Foster on 5 live Drive from Kathmandu and said this was "a tragedy that could've been prevented". He also describes what it was like up there, saying he and many others were trapped "at 17,000 feet, in white out conditions, with no map, no compass and no knowledge of the area".
