As Prince Philip preps for retirement this Fall, Queen Elizabeth II is setting some ground rules for the rest of the royal family, especially Prince William and Prince Harry. According to the Sunday Times, the queen has suggested that her grandsons put more emphasis on state duties. Over the past few months, the royal brothers have opened up about the death of their mother, Princess Diana, as part of the Heads Together mental health campaign, but a royal source claims that "soul-baring" isn't what Buckingham Palace wants from them. "The direct impact [of Prince Philip's retirement] will be that the Cambridges will be expected to step up and undertake more state business and do less of their campaign work." We, for one, think the younger royals are doing a great job decreasing the stigma surrounding mental illness and ultimately carrying on their mother's legacy.
