Bedfordshire Fire and Rescue were called to the scene and created a fire break, a strip of open space, so as the blaze was under control.
Simon said: “I was heading into Leighton at about 7.30pm and from the Eggington turn there was a blaze.
“This photo I took was at 9pm off Hockliffe Road, as I passed back on my way home.”
A Bedfordshire Fire and Rescue spokeswoman said: “On Model Farm, Leighton Road, there was a large haystack fire of 30m x 10m – 600 bales of hay.

“The fire break has been extended and it has been left in the care of the farmer.”
