Today, 3 October, 2014 is National Potato Day, a day that celebrates all things potato.

In honour of the potato, we take a look at how Tayto crisps are made in 1970. From the raw ingredient of the potato to the end product as a cheese and onion crisp.

The report by Brenda Kneafsey from the programme 'Motley' was broadcast on 19 September, 1970.
