Initially it was Sir Neville Chamberlain, who declared war on Germany on 3rd September 1939 following Hitler's invasion of Poland in breach of the Munich Agreement. Chamberlain sent a massive British Expeditionary Force into France to help the French defend their country against Nazi invasion, but was forced to resign in February 1940 following the disastrous British retreat from Dunkirk.
He was replaced by Winston Churchill, who headed a Coalition Government until the end of the war in Europe in May 1945. Soon afterwards a General Election was called, which saw Churchill replaced by the Labour government of Clement Attlee. It was Attlee who was in power when the war against Japan ended, in August '45.
