The sight of a Palestinian flag at the opera has left Britain trembling in fear of where it might appear next. Here are the next seven occasions where audiences could be shocked and horrified:

Les Miserables in the West End: Audiences expecting a neutral tricolour might find their evening ruined by unexpected politics.

An Oasis gig: What if the Gallaghers pick up a flag thrown on stage? It might even interrupt everyone's favorite bathroom break during 'Cast No Shadow.'

The 2025 Labour Party conference: Delegates might be horrified to find themselves sharing a stage with this divisive symbol. Arrests could ensue!

A protest outside a migrant hotel: Hard-working families might be mortified to be seen as political during their stone-throwing festivities.

A pornographic video: Imagine the horror of reaching a climax when suddenly a flag appears, making your reaction an endorsement of the cause.

Avatar: Fire and Ash: A blockbuster with cutting-edge CGI might be forever tarnished by a flag hidden in a crowd scene.

Christmas: Surely, even the left wouldn't ruin the festive season with flag appearances during this time of goodwill.
