Former Senator and Presidential candidate George McGovern has died of natural causes at the age of 90 at a hospice in the US, while surrounded by family and friends. Although widely considered a pacifist, due to his outspoken views on the Vietnam War, while serving as a pilot during World War Two, McGovern had wanted to bomb rail tracks near to Auschwitz, to stop the flow of Jews and others into the Nazi death camp, but was overruled. Democrat McGovern served as Senator for South Dakota from 1963 to 1981 and challenged Richard Nixon for the US Presidency in 1972. However, McGovern suffered a landslide defeat, winning just two states and less than forty per cent of the popular vote. McGovern was also instrumental in setting up the World Food Programme. Helater established a nutritional programme which provided meals for millions of children around the world, which earned him the title of co-winner in 2008 of the World Food Prize.
