The Edinburgh Dungeon said the one-day event is in revenge for the Battle of Falkirk, fought 710 years ago July 21st, at which more than 2,000 Scots were slaughtered by the Auld Enemy.

English visitors will only be allowed entry if they sign a scroll swearing allegiance to Scotland, while those from other countries will be encouraged to bring in items deemed 'typically English’ to be smashed.

The attraction, which is visited by 200,000 people per year insisted the measures were a fitting tribute to the Scots soldiers who were killed and their leader, William Wallace.

But it faces a growing backlash from English tourists appalled that they were being singled out for something that happened so long ago.
