SurreyGuy - // What was so bad about these pictures that they've caused him to pull out of giving his daughter away?//
As I understand it, Mr Markle has arranged with an agency to have pictures taken with his knowledge, in a manner that suggests they were taken without his knowledge, and then he has split the resulting fees with the agency.
This is not uncommon, but in view of his relationship with the future royal bride, Kensington Palace has got somewhat het up about it, and now he is too embarrassed / ill (not sure which yet) to come over and walk his daughter down the isle.
