Yes or no?

Blue has been the dominant colour today. Not just north of the border. I flew to Munich on a day trip to drive the new Volkswagen Touareg, and it felt like a mid-summer day, with warm weather and a vivid blue sky from one horizon to the other.

There were signs of autumn though, such as the bright mounds of pumpkins at various points alongside the country roads, put there for passing drivers to stop and buy them ready for Halloween.

It is going to be a very long night. History is being made. Will the British flag be less blue by the morning? We'll soon know.
