It is the latest value offer from M&S, which announced last week it was extending its price lock on 150 items until the Autumn.

M&S Food managing director Alex Freudmann said: “We know value is everything to our customers right now, and while they’re looking forward to a great summer, they’re also looking for certainty on spending.

“We’re determined to keep up the pace for our customers. Our value perception is at its highest point in six years because we are relentlessly focused on price with no compromise to the magic of M&S Food – our market leading product quality, innovation and sourcing standards.”
