September 30, 1938: 'Peace for our time' - Chamberlain
The British Prime Minister has been hailed as bringing "peace to Europe" after signing a non-aggression pact with Germany.
PM Neville Chamberlain arrived back in the UK today, holding an agreement signed by Adolf Hitler which stated the German leader's desire never to go to war with Britain again.
The two men met at the Munich conference between Britain, Germany, Italy and France yesterday, convened to decide the future of Czechoslovakia's Sudetenland.

A year later the German leader derided the agreement as just a "scrap of paper" and invaded Poland on 1 September 1939.
