Oh for the love of God. The Empire Windrush landed a few years before the coronation - 70+ years ago. You'd think that someone somewhere in the palace would have pointed out that, from a purely self-interested point-of-view, and however racist the members and institution of the royal family may be, the positive PR from having a mixed race marriage/children within the royal family would be invaluable in what is perceived (rightly IMHO) as an outdated and unnecessarily tradition. The only real chance of the dynasty surviving through the 21st century is to convince the public that Harry and William are different from the older generation and can play a useful role in modern Britain taking over the Princess Diana politics role. But no, obviously a 1/4 black child who going to be at least 4th+ in line to the throne would be a major constitutional crisis.
