In part this has been caused by the second wettest summer in the UK since records began (according to Met Office statistics), which follow the worst drought in the US in 50 years and a heat wave in Russia.

BPC Chief Executive Peter Bradnock said: “The costs of wheat, soyameal and corn – which are the key feed ingredients for the poultry industry and a number of other sectors – have increased significantly this year. For several months we have warned that British poultry producers are under real pressure from global factors and are pleased that the British Retail Consortium has accepted this will lead to a rise in shop prices.

“If consumers are to continue to enjoy the secure supply of British poultry, food prices need to accurately reflect cost increases.”
