Prince Harry and wife Meghan Markle were excluded from the Duke of Westminster's wedding invite list as his loyalty has to be to the King and future King, a royal insider has claimed.
The Sussexes have been snubbed by Hugh Grosvenor, who decided not to invite them to his wedding with Olivia Henson next year in a bid to avoid 'drama', it is claimed.
Despite the fact he is believed to be godfather to the Sussexes' son, Prince Archie, and one of Harry's oldest friends, it is claimed the Duke has not invited him so it won't overshadow his big day.
A source says one of the reasons Harry and Meghan have been left out is because they have criticised the royals and their way of life.
'You have to remember that people like this are very traditional - and while they wouldn't be at all bothered by a drunken uncle or some overt snogging on the dance floor, they don't like it when people criticise their way of life in public, which is exactly what Harry and Meghan have been doing for the last few years,' the source who knows the Grosvenors told the Telegraph.

The source said the Duke of Westminster's loyalty would have to lie with the King and future King
'And given who he is, Hugh's loyalty would always have to be to the current King and the future King.'
One of Britain's richest men, the 32-year-old billionaire aristocrat proposed to fiancee Olivia Henson at his family seat, Eaton Hall in Cheshire.
They are set to get married at Chester Cathedral in June in the wedding of the year.
William and Kate and the King and the Queen are all invited, with the Prince of Wales even thought to be in the running to be best man.
The Duke of Westminster had originally planned to invite Harry and Meghan, but the aristocrat changed his mind, fearing their presence would overshadow the day, The Sunday Times reports.
Another serious consideration was said to be the feelings of Charles, Camilla, William and Kate, who are all likely to be there.

A friend of the pair told the paper: 'It's incredibly sad it has come to this. Hugh is one of very few close friends of William and Harry's who has maintained strong bonds and a line of communication with both.
'He wishes they could put their heads together and patch things up, but realises it's unlikely to happen before the wedding.
'He wanted to avoid anything overshadowing the day, especially for Olivia, and doesn't want any awkwardness.'
A spokesman for the Duke earlier said: 'We are not in a position to comment on the guest list.' Buckingham Palace also previously declined to comment.
