Sylvia Tidy-Harris, who is a judge for the Orange National Business Awards, says David often does beat Goliath.

She said that tyre giant Goodyear Dunlop had come up with the 'run flat' tyre - seen as a major safety breakthrough - which was up against a biodegradable sandwich box, invented by the tiny snack firm FooGoo.

Writing in her Daily Telegraph Viewpoint column, Sylvia said:

"Impressive though the tyre was, it could only be fitted to certain high-value cars. But FooGoo had made something we could all see appearing in our local sandwich shop. Yes, they won."
