Melt the white chocolate over low heat in a saucepan then leave to cool for a minute or two.
Add the digestive biscuits and pretzels to a large bowl then crush them into medium-sized pieces using your hands or the end of a rolling pin. Then stir in the marshmallows, popcorn and glace cherries.
Pour the melted white chocolate into the bowl and mix until everything is evenly covered. Transfer the mixture to your tin and press down into place.
Refrigerate for around 2 hours then cut into squares and enjoy!
