Don't even THINK about bringing it up.
Prince Harry and Meghan Markle are heading off on their first international visit – although, admittedly, it's not very far from home.
The pair will visit Ireland on the 10th and 11th July (straight after Prince Louis' christening), and are reportedly 'looking forward to learning more about Ireland's history and experiencing its rich culture, as well as meeting the people who are shaping the country's future.'
Although the full itinerary of their visit is yet to be announced, it's reported that they are likely to pay a visit to the Guinness Storehouse while in Dublin.
However, there is one conversation topic will definitely be off the cards during their meeting and greeting.
It's a fairly controversial one, so we can't say we're surprised.
Royal decrees have been issued to Irish ministers instructing them not to bring up Brexit with the Duke and Duchess.
Members of the royal family are supposed to remain neutral when it comes to politics, and therefore Harry and Meghan will not be able to comment on such matters.
The same instructions were issued when Prince Charles and Camilla visited the country recently.
To be honest, we'd rather like to issue the same rule for all family dinners...
