A royal year from hell: Is this new-look monarchy now more fragile than ever?

King Charles' rise to the throne was a chance for the royal family to reset and refresh.

Under the new king, family feuds faded and new projects were on the horizon as the monarchy was quietly stripped back to just a handful of working royals.

But just months into the job, Charles' best-laid plans have been thrown into turmoil by some very personal crises.

First came the shock announcement that the King had been diagnosed with cancer, forcing him to step back from official duties.

Then his beloved daughter-in-law Catherine, the Princess of Wales, mysteriously vanished from the public eye, re-emerging months later with some devastating news of her own.

And in the middle of it all, Prince William - husband, son and heir to the throne - suddenly found himself bearing the weight of the House of Windsor on his shoulders.

A Royal Year From Hell, part of the new series 9News Investigates, breaks down the events that have shaken the Royal Family in the past year, and the secrets, mistakes and mishaps that have forced them to embrace a new era of transparency with their public.

The show must go on, but is this new-look monarchy now more fragile than ever?
