Sad fact is that no region in England or Scotland has enough interest in rallying to organise a WRC event.
Like Wales, N.Ireland has that interest as its people are big rally fans. Plus it has a great rally scene and WRC drivers Meeke (& Breen).
They also seem confident it can be funded even without a functioning Stormont.
I think it would be brilliant. Not the same as Wales of course but still brilliant.
