The Norway Debate, sometimes called the Narvik Debate, was a momentous debate in the British House of Commons during the Second World War from 7 to 9 May 1940. It has been called the most far-reaching parliamentary debate of the twentieth century. At the end of the second day, the members held a vote of no confidence which was won by the government, but with a drastically reduced majority.
After the Allies failed to prevent the German occupation of Norway, the Commons held an open debate from 7 to 9 May on the government's conduct of the war. This has come to be known as the Norway Debate and is renowned as one of the most significant events in parliamentary history.
