LONDON—The introduction of full customs checks between Britain and Northern Ireland risks becoming “incendiary” when prices rise and favourite products fail to get through, one of the country’s biggest retailers said.

Archie Norman, the chairman of Marks & Spencer, told BBC Radio that the planned introduction of full post-Brexit checks in October would be “business destructive” and prevent the food and clothing retailer from providing its full range.
