Family or not, Queen Elizabeth II is making it known that she's not one to mess with when it comes to protecting the monarchy.

There is no denying that 2019 has been quite the year for the British royal family, and not in a good way. The potential "annus horribilis" involved Meghan Markle and Prince Harry publically addressing their struggles with the British tabloids and, more recently, the controversy surrounding Prince Andrew.

In light of everything that's happened, some had thought that Queen Elizabeth had lost control of the monarchy, however, her latest actions prove the opposite.

"This is a warning to any of the younger royals, particularly Meghan and Harry, that she won’t tolerate them stepping out of line," a royal source said of Prince Andrew stepping down from his royal duties. "She was not happy with the TV interview they did and them generally doing their own thing."

"The house of York has a history of doing its own thing, and look where that has got them," the source continued. "The Sussexes need to take heed, keep their heads down, do a programme of British engagements up and down the country and most of all do as they’re told."

As the year is winding down, royal watchers will likely hope to see the drama surrounding the royal family disappears. After all, Queen Elizabeth is currently 93-years-old and already has her son Prince Charles stepping in to fulfill some of her responsibilities. Of course, there is always the option to end the monarchy, which was suggested by TV commentator Kevin Maguire.

"We’re holding on to a much-broken line coming from warlords which we change every now and again. You say no one will have a go at the Queen - alright, she can stay there for the end but I’d like her to be 'Elizabeth The Last,'" he said while appearing on Jeremy Vine on 5 in October.

He added, "Let’s not go down Sweden’s way, let’s get down France’s road and have a republic. It will be Great Britain."
