<P> I am speaking to you from the Cabinet Room at 10, Downing Street . </P> <P> This morning the British Ambassador in Berlin Nevile Henderson handed the German Government a final note stating that unless we heard from them by 11 o'clock, that they were prepared at once to withdraw their troops from Poland, that a state of war would exist between us . </P> <P> I have to tell you now that no such undertaking has been received, and that consequently this country is at war with Germany . </P> <P> You can imagine what a bitter blow it is to me that all my long struggle to win peace has failed . Yet I cannot believe that there is anything more or anything different that I could have done and that would have been more successful . </P>
