A couple from Eye had agreed to support Fascism during the Second World War, recently uncovered secret Service files have revealed.

The MI5 sources uncovered intelligence of farmers Ronald and Rita Creasy, who had promised to commodate Nazi spies and tip off the Germans if they heard of any Allied attack plans.

The reports also detailed how the pair exchanged Nazi salutes with workers at their farm.

One of their communications which was intercepted was a Christmas card sent to the founder of the British Union of Fascists, Oswald Mosley in 1943.

An intelligence report dated March 1943 explained how the Creasys offered to pass on useful information to the Germans because it would assist Mosley.

It read: 'They were offering their help because they knew that if Hitler lost the war then Mosley would also lose.

'As they would do anything to bring Mosley into power, they were willing to help Germany.'

It stated that the Creasys claimed they had been tipped off by local soldiers about plans for an Allied raid, and pledged to pass similar information on in the future.

'He promised... that if they got hold of news similar to the Dieppe raid affair or any definite news about the opening of a second front he would send Mrs Creasy to London with the news unless some alternative form of communication was suggested.'

It went on: 'The Creasys were willing to rent rooms to German agents in the event of an emergency, or alternatively to accept them as paying guests.'

The intelligence source reported that Mrs Creasy was 'easily the more pro-Nazi of the two and by far the more dangerous to the British'.

Another file claimed the Creasys were 'delighted' to have been given a photograph of Adolf Hitler.

The Secret Service files date from September 1939 to February 1957, and have been unveiled for the first time at the National Archives in Kew, west London.

Professor Christopher Andrew, the official historian of the Security Service, said that the Creasys were victims of a lone MI5 agent who secretly penetrated the ranks of Britain's wartime Nazi sympathisers.

Documents released last year revealed how the agent - operating under the alias Jack King - controlled the activities of hundreds of 'Fifth Columnists', neutralising the threat to Britain's war effort.

Prof Andrew said: 'The latest declassified files identify two more members of the Jack King network - a married couple named Ronald and Rita Creasy.

'In 1943 Ronald Creasy offered to provide safe accommodation for both German agents and parachutists who landed in England. Like the rest of the Jack King network, he had no idea that King passed his offer not to the Gestapo but to MI5.'
