In a text message to members, the club said the soil had come from a site which had a “history of bombs landing there during World War Two”.

It continued: “These bombs were often released by planes returning from missions to ensure they landed safely.

“The area, now being developed for housing, was excavated this morning.

“Unfortunately, one of these bombs was unearthed, encased in soil, and transported by lorry to the golf course.

“Upon arrival, it was spotted by the TJ digger driver while being unloaded. Their quick thinking and immediate action in raising the alarm have been praised by the police.”

Mr Pearson said the soil was needed to construct a reservoir near the 18th green.

Hampshire and Isle of Wight Constabulary said it had been called to the site at about 14:30 GMT and officers remained on site.
