The supermarket chain launched its British game range after receiving requests from customers who were looking for an alternative to beef, chicken, pork and lamb.
The new range includes pheasant, partridge, rabbit and venison.
It has been sourced from the Scottish Borders, Nottinghamshire, County Durham, Yorkshire and Northumberland.
A spokesperson for M&S said: “As it is sourced from the wild, game develops stronger muscles than farmed meat and poultry giving the meat a firmer texture and a distinctive taste, derived from the land they live on.
“They have a lean, virtually fat free meat, making game a healthier alternative to other meats such as beef.
“The new range will be hung for two days to ensure that the flavour whilst distinctive, remains mild enough for customers to enjoy.”
