“Although the King is carrying out his duties with typical determination, he has had to accept limitations during his cancer treatment," royal biographer Sally Bedell Smith told People. "As a result William has been taking on more responsibilities, and he and Kate have been preparing for their future roles sooner than they would have expected.”

As Kate Middleton continues her recovery, she’s confronting the looming responsibilities of her future role as Queen sooner than expected. Plans continue to be made behind the scenes for Prince William’s eventual succession,

Kate Middleton has eased back into public life after facing her own health struggles this year. The Princess of Wales announced in March that she’d been diagnosed with cancer, like King Charles. In September, she confirmed she’d completed chemotherapy and was now cancer-free.

It's no secret that Kate Middleton will one day become Queen of the United Kingdom. According to People, King Charles III has "accepted limitations during his cancer treatment," allowing Prince William to take on more duties in recent months.

After the Princess of Wales announced that she's finally cancer free, the pair have made a gradual return to public-facing duties.
