Original sentence: He was challenged in 1992 as leader of the Social Democrats by Poul Nyrup Rasmussen, who went on to win the internal election.In 1987 Svend Auken succeeded Jørgensen as leader of the Danish Social Democrats, in opposition to the governments of Prime Minister Poul Schlüter.Subsequently, this has happened to Mogens Lykketoft (leader from 2002 to 2005) as well.Svend Auken is generally acknowledged to be one of the most naturally gifted and charismatic Danish politicians of his generation, and he is sometimes referred to (by those who like him) as "the best Prime Minister Denmark never had".That gave Auken the dubious honour of being the first Social Democratic leader since 1910 to not become prime minister.Until his death, he was the EU-affairs spokesman of his party, and he also kept a high profile on environmental issues
