there is no widely known or prominent "Laundry family" that has left the United Kingdom or has been specifically associated with a high-profile departure from the country. It's possible that events or circumstances might have changed , or there might be lesser-known individuals or families with the last name "Laundry" that are not widely covered in the media.
If you are referring to a specific event or individual related to the "Laundry family," I recommend checking recent news sources for the most up-to-date information. Keep in mind that my information might be outdated, and I don't have access to real-time data.
