More than 50 Second World War history groups will be at the event along with military vehicles, vintage shopping stalls and fun for all the family.

In the marquee during the daytime there will be singing and dancing, period radio shows, swing dance lessons and fashion shows.

There will be a licensed bar and tea rooms, plus vintage caravan and period farm machinery displays.

The BBMF will feature flypasts of the Spitfire, Hurricane and the Dakota over the weekend along with the "biggest and best ever" battle that will feature tanks and heavy armour from the Second World War with re-enactors.

Organiser, Matt Page, said: "This year especially remembrance is at the heart of the event.

"Hundreds of re-enactors will bring the battle zones to life wearing period clothes, giving 21st century visitors the closest experience to time travel they can get."

On Sunday morning there will be a Drum Head service held in the main marquee at 11 am (open to all visitors) and a "poppy shower" tribute on the afternoon.

The event will take place at Grounds Event Site in Knights End from Thursday July 18 to Sunday July 21.
