It had been a few years since Carole and Pippa Middleton last enjoyed a mother-daughter Wimbledon day and they were probably very careful not to breach the rules when they arrived to watch the tennis on 6th July. The Princess of Wales's mother and sister cheered the players on from the Royal Box where only invitees are allowed.
They've sat there before, but this wasn't the case in 2017 after Carole and Pippa were allegedly denied entry over an awkward mistake. According to Hello!, they arrived late to watch Andy Murray's match against Benoit Paire and so had to take standard seats.
