During the war the British formed Stay-Behind groups with SOE personnel in Sweden. The man behind this was Wilfred Latham, called "the greek", a rather anonymus clerk at the British Embassy working under his boss the military attache Crofts. Latham was not popular among the Swedish Secret Service, becuse he went around and took photos of the men who were watching the embassy. The groups would operate in case of a german occupation or if the transit traffic by rail Germany-Norway would be to large. There were several teachers in radiotelegraphy, many Norwegians, such as John Palle Thu, AVOCET, and Knut Kjerland, OSPREY. There should be a report from the Security Police from April 1943. A professional criminal Norwegian by the name Thomas Randolf Meyer disclosed what he knew, in the groups there were Brits such as Ronald Turnbull, "Hawkuck", Albert Bleakley, "Nilsson", who dealt with the connections betwwen the groups and Reidar Hedemann, journalist at the Norwegian legation. The Security Police discovered the operation and several persons were expelled to Britain (including Thu and Kjerland) The Stay-behind groups were supposed to be located in towns like Stockholm (3 groups), Borås, Helsingborg, Göteborg, Linköping, Norrköping, Södertälje, Växjö, Västerås och Örebro. Has anyone more information about this?
