Britain's Prince Charles was photographed pouring a pint of Guinness during a visit to London's Irish Cultural Centre yesterday.
He's the latest in a long line of well-known figures to be pictured with a pint of the black stuff.
Alcohol Action Ireland chief executive, Sheila Gilheany, says we have to question why this happens
"And yet again, you have a royal celebrity of some description, you know, appearing, and being associated with things Irish which is lovely, but one of those things is pulling a pint. And you really have to ask yourself what and why does this happen? And it doesn't happen by accident, it happens through an industry actually actively promoting their product, and I think we just have to bear that in mind"
