The Mail on Sunday are claiming that Charles has asked the Archbishop to talk to Harry to get him to attend the Coronation. But William is against this as he fears the Sussex's will detract from the Coronation.
"Harry could be guaranteed a high-profile seating position in the Abbey or an informal assurance that he will be able to keep his titles as an inducement to attend. However, William fears that unless Harry’s visit is tightly scripted, he could steal the limelight by, for example, going on a walkabout in a deprived London borough with Meghan."
