In celebration of British Sandwich Week, YouGov polled the nation on what shape a sandwich should be. The results show that 60% of British people prefer their lunch in a rectangle, and 28% in a triangle.

This week is #BritishSandwichWeek, and we've settled one of the nation's biggest sandwich arguments: which shape is best?

The rest of the respondents seemed a bit confused, with 5% saying they prefer a sandwich in some other shape, 2% don’t know, and 5% never make sandwiches for themselves.

The poll showed that women are more likely to favour triangular sandwiches, with 35% saying they prefer that shape to 21% of men.

The nation's favourite sandwich was confirmed as cheese, with 36% of respondents saying the dairy product is their filling of choice. Slightly weirdly, mayonnaise came in second at 20%. The remaining favourite sandwich fillings are ham, at 16%, tomato, at 15%, and egg, tuna, and chicken in joint fifth place at 11% each.
