Input: Consider Input: Question: How many nations comprise the organization that Albania complained to concerning Royal Navy conducting mine-clearing operations in Albanian territorial waters, Passage:The Corfu Channel Incident refers to three separate incidents involving Royal Navy ships in the Straits of Corfu which took place in 1946, and it is considered an early episode of the Cold War. During the first incident, Royal Navy ships came under fire from Albanian fortifications. The second incident involved Royal Navy ships striking mines and the third incident occurred when the Royal Navy conducted mine-clearing operations in the Corfu Channel, but in Albanian territorial waters, and Albania complained about them to the United Nations. This series of incidents led to the Corfu Channel Case, where the United Kingdom brought a case against the People's Republic of Albania to the International Court of Justice. Because of the incidents, Britain, in 1946, broke off talks with Albania aimed at establishing diplomatic relations between the two countries. Diplomatic relations were only restored in 1991.

Muir and Norden's first joint venture was a radio show for both performers, Take it from Here!, which they scripted from 1948 to 1959. They went on to write many successful radio and television scripts, including Whack-O! (19561960) and three series of Faces of Jim (19611963) which were vehicles for Jimmy Edwards. They also wrote the satirical sketch Balham, Gateway to the South for the BBC Third Programme.
