Meghan follows Princess Diana's footsteps

They will make their promises, to live together for good and for bad, for riches and for a lifetime.

But there is a traditional promise that Meghan will not make to her husband - a promise of obedience.

But Meghan is not the first queen to leave this promise without making it. Nor had Princess Diana made such a promise, which she became her mother - in - law who married Prince Charles in 1981.

Unlike them, Kate Middleton, even though the modern bride had made such a promise.
