Tesco has introduced new season-fresh English sweetcorn into stores this week that it claims is sweeter than normal ­because of the weather.

Although the recent lack of rain had reduced yields this season, the sunny ­conditions meant the product was superior, said Kelly Northcroft, account executive at Barfoots of Botley. "The quality of the corn will be excellent; tasting extra-sweet and very succulent."

Penetration of fresh sweetcorn had increased from 10% to 30% over the past few years, said Tesco.
