Several days passed before, under British pressure with US diplomatic backing, the Yugoslav troops withdrew from the city proper, not before establishing a parallel Carinthian-Slovene civil administration (the "Carinthian National Council") which was presided over by Franc Petek. However, protected by British soldiers, the members of the Provisional State Government went about devising a comprehensive programme to cover the new political, sociological, and economic outlooks in the land, which would serve the British military authorities. Rapid financial assistance and the restitution of property to the victims of the Nazi regime was necessary. This posed a problem, because one of the first actions of the British had been to confiscate all the property of the Nazi Party, as well as to freeze their bank accounts and to block their financial transfers. It took months before basic communication and public transport, mail service and supply were working again, to some extent at least. During the years that followed these turbulent days, a major part of the British Eighth Army, which in July 1945 was re-constituted as "British Troops in Austria" (BTA), had their headquarters in Klagenfurt - as Carinthia, together with neighbouring Styria, formed part of the British occupation zone in liberated Austria, which remained to be the case until 26 October 1955.
