Mum has spent the last 20 years amassing collection of 250 ultra-rare limited edition snacks

A 43-year-old mum has spent the last 20 years amassing an enormous collection of 250 ultra-rare limited edition snacks - including an original 37-year-old Marathon bar.

Food-lover Ali Smith's impressive selection of goodies includes oddly-flavoured crisps, chocolate bars, biscuits, baked beans and even tomato sauce. Her most prized possession is a Marathon bar dating back to 1982 which she bought on eBay two decades ago for £25.
