The Saltire is the flag of St Andrews, a white diagonal; cross on a blue field, supposedly the Christian symbol for the crux decussate, the shape on which the saint was crucified. But it means more than that.
It is iconically Scotland: Murrayfield in the annual battle against England; Bruce and Bannockburn and the battle against King Edward’s England - any battle against England.
And in case Ed Miliband - who has called on people across the UK to fly the flag - doesn’t know, it’s the oldest continuous sovereign flag in the world.
It was incorporated into the design of the Union Jack – but doesn’t represent the Union.
When the early Scottish nationalists were looking for a representative symbol they struggled, because the Saltire wasn’t theirs.
