The FSA found some imported Dubai-style chocolate products may not have been intended for sale in the UK and therefore lack a full ingredients list or allergen labelling that are legally required.

Professor Robin May, the FSA's chief chief scientific advisor, said: "Some imported Dubai-style chocolate products don't meet our standards and could be a food safety risk, especially for consumers with allergies."

The FSA said it had worked with local authorities to identify a number of Dubai chocolate products that posed a health risk to consumers with allergies.

The FSA website says that if food is sold online or over the phone through "distance selling" then allergen information must be provided at two different stages in the order process.

The FSA's head of women's football Deborah Dilworth said the trials were a chance to be "innovative, creative and offer more choice to supporters".
