Sir: Last week’s ruling by the Supreme Court on the Greek yoghurt dispute (2 August, p42) underlines the position that ‘Greek yoghurt’ is a recognised term in the minds of the public and can only be applied to yoghurt originating from Greece and being made in the long-established manner. 

Some food producers may be puzzled given Greek yoghurt is neither a PDO, such as Jersey Royal potatoes, nor a PGI, such as Whitstable oysters. 

In the UK, however, the law is different to much of Europe in protecting names used extensively and recognised as such by the public. This case confirmed the courts here will prevent a food producer from using a description if this results in the public being misled.
