Farmers and retailers are warning that the second wettest summer on record will lead to food prices rising.
According to the National Farmers' Union wheat yields in England are down by almost 15% on the five-year average.
The world price of grain has already been rising in recent months.
Some farmers in Cambridgeshire say they've never known a summer like it.
