Mark Ludmon’s letter in The Guardian is worth quoting in full:
You quote Boris Johnson as referring to Italy’s reliance on the UK for buying its prosecco (UK aims to trigger Brexit process in early 2017, 23 September). He claimed Britons drank a phenomenal 300m litres of prosecco a year, but, according to official figures, UK sales of prosecco were 40m litres in 2015. In fact, Italy produced only 270m litres of prosecco in total last year, according to the Prosecco DOC Consortium of growers. This means that the UK accounted for only 15% of prosecco volume sales, with other countries such as Germany and the US just as thirsty for the wine. Just the latest example of the weaknesses in the government’s chaotic thinking over Brexit.
Johnson never lets the truth get in the way of a good speech.
