Though every government of the Weimar Republic had violated Part V of Versailles, in 1933 and 1934, the Nazi government had become more flagrant and open in violating Part V. In 1933, the Germans started to build their first U-boats since World War I, and in April 1935, launched their first U-boats.[27] On 25 April 1935, the UK's naval attaché to Germany, Captain Gerard Muirhead-Gould was officially informed by Captain Leopold Bürkner of the Reichsmarine that Germany had laid down twelve 250 ton U-boats at Kiel.[28] On 29 April 1935, the Foreign Secretary Sir John Simon informed the British House of Commons that Germany was now building U-boats.[28] On 2 May 1935, the Prime Minister Ramsay MacDonald told the House of his government's intention to reach a naval pact to regulate the future growth of the German Navy.[28]
