Ahead of this year’s parade, Ballymacarrett District LOL No 6 has asked everyone involved or attending to do so in “remembrance” and with “dignity, respect, and gratitude.”

A post on Facebook adds: “The past few years has witnessed an alarming rise in crowds of young people consuming alcohol and encroaching into the parade.

“Indeed, the crowd encroachment is prevalent along most of the Newtownards Road from McDonalds until after the Skainos Centre.

“Remember, the reason for the parade is to remember with respect and dignity.”
