Cold and wet weather also thought to have led to more lambs dying in early season, as Morrison drops 100% British lamb pledge
The price of British lamb has hit an all-time high as cold weather and disease in the UK and difficulties with imports have combined with a surge in demand.
Wholesale prices have soared by more than 40% year-on-year to more than £8.50 a kg , while the amount of lamb expected to be produced in the UK this year is forecast to shrink by 1.4%, according to the Agriculture and Horticulture Development Board (AHDB).
